1According to the official Prüfungsschwerpunkte Chemie 2026 (Leistungskurs, Land Berlin), how is a Prüfungsaufgabe structured and how many tasks must the candidate complete?
A.Two tasks are set and both must be completed in full
B.Four tasks are set, of which the candidate must choose and complete three
C.Six short tasks are set and the teacher selects four of them
D.One compulsory task plus one of three optional tasks
Explanation: The Berlin central Abitur in Chemie presents a Prüfungsaufgabe consisting of four coherent, material-based tasks (Aufgaben). The Prüfling alone decides which three of the four to work on; the teacher makes no selection.
2What is the total working time for the 2026 Berlin Abitur Chemie at Leistungskurs (erhöhtes Anforderungsniveau), and what does it include?
A.255 minutes of pure writing time
B.315 minutes without any reading allowance
C.300 minutes, including 30 minutes of individual reading and task-selection time
D.240 minutes plus a separate 60-minute oral component
Explanation: The Prüfungsschwerpunkte Chemie 2026 (Leistungskurs) set the Arbeitszeit at 300 minutes, which explicitly includes a 30-minute individual Lese- und Auswahlzeit for reading the tasks and choosing three of them. The Grundkurs (3. Prüfungsfach) version is 255 minutes.
3Which aids (Hilfsmittel) are permitted in the 2026 Berlin Abiturprüfung Chemie?
A.A German spelling reference, an introduced Formelsammlung matching the IQB mathematical-scientific formula collection, and the introduced Taschenrechner
B.Only the periodic table printed on the exam paper
C.Any personal annotated textbook and a laptop with offline software
D.No aids of any kind are permitted
Explanation: The PS 2026 Chemie lists exactly three aids: a current Nachschlagewerk of German Rechtschreibung, a Formelsammlung introduced in class that corresponds in content to the IQB mathematisch-naturwissenschaftliche Formelsammlung, and the Taschenrechner introduced in class.
4A candidate in the Berlin Chemie Abitur chooses the task that contains a fachpraktische (experimentelle) Teilaufgabe. What does the PS 2026 say about the consequences?
A.The candidate loses Bewertungseinheiten automatically for choosing the practical task
B.The practical task is only available in the Grundkurs, not the Leistungskurs
C.The candidate must finish in the same 300 minutes like everyone else
D.The total working time may be extended by up to 60 minutes, as indicated in the task, and this extension is recorded in the Prüfungsprotokoll
Explanation: One of the four tasks is usually offered with an experimental sub-task. Choosing it can extend the working time by up to 60 minutes; the task states the extension, and the supervising teacher notes it in the exam protocol. If Ersatzergebnisse (provided measurements, photos) are used instead of own measurements, the task states how many Bewertungseinheiten are then not awarded.
5How do the Leistungsfach (Leistungskurs) and the 3. Prüfungsfach (Grundkurs) written exams in Chemie differ in Berlin 2026?
A.They are identical in time and depth; only the course name differs
B.The Grundkurs exam contains only multiple-choice items
C.The Leistungskurs exam lasts 300 minutes at erhöhtes Anforderungsniveau with deeper mathematisation and model complexity, while the Grundkurs (3. PF) lasts 255 minutes at grundlegendes Anforderungsniveau
D.The Leistungskurs exam is oral, the Grundkurs exam is written
Explanation: Both levels share the joint Berlin-Brandenburg central task structure (four tasks, choose three), but the Leistungskurs is examined at erhöhtes Anforderungsniveau for 300 minutes, while the 3. Prüfungsfach at Grundkurs level runs 255 minutes at grundlegendes Anforderungsniveau. The RLP 2021 specifies additional LK-only content (e.g. Indikatorfarbstoffe, Nernst equation, radical polymerisation mechanism).
6In the marking of the Berlin Chemie Abitur, what does the rule on Fehlerfortsetzung (error carried forward) state?
A.Correctly performed subsequent steps that build on an earlier wrong intermediate result receive the stated Bewertungseinheiten, unless the error made the steps substantially simpler
B.Any single numerical error leads to zero points for the whole task
C.Half Bewertungseinheiten may be awarded at the examiner's discretion
D.Only the final answer is marked; intermediate steps are ignored
Explanation: The PS 2026 states that for correctly executed partial steps into which a wrong intermediate result entered, the given number of Bewertungseinheiten is awarded — unless the earlier error substantially simplified the step. Only whole Bewertungseinheiten may be given.
7The KMK Bildungsstandards (BiStas AHR) Chemie name four Inhaltsbereiche that Berlin exam tasks draw on. Which set is correct?
A.Mechanik, Optik, Elektrizitätslehre, Thermodynamik
B.Atomistik, Pharmazie, Geochemie, Biochemie
C.Anorganik, Organik, Physikalische Chemie, Technische Chemie
D.Stoffe, Strukturen, Eigenschaften; Chemische Reaktionen; Arbeitsweisen; Lebenswelt und Gesellschaft
Explanation: The four Inhaltsbereiche of the KMK Bildungsstandards for Chemistry are: Stoffe, Strukturen, Eigenschaften; Chemische Reaktionen; Arbeitsweisen; and Lebenswelt und Gesellschaft. Every Berlin exam task states its Inhaltsbereich and covers at least three Kurshalbjahre of the Qualifikationsphase.
8Which statement correctly describes the structure of an α-amino acid in aqueous solution at neutral pH?
A.It exists exclusively as an uncharged molecule with NH2 and COOH groups
B.It exists predominantly as a Zwitterion carrying a protonated amino group (–NH3+) and a deprotonated carboxyl group (–COO−)
C.It is always doubly positively charged
D.It decomposes immediately into ammonia and carbon dioxide
Explanation: In aqueous solution an α-amino acid undergoes an internal proton transfer: the carboxyl group donates a proton to the amino group, forming a Zwitterion with –NH3+ and –COO−. This ionic character explains the high melting points and good water solubility of amino acids.
9In the Biuret-Reaktion a few drops of dilute copper(II)-sulfate solution are added to a protein solution made alkaline with sodium hydroxide. Which observation proves peptide bonds, and which species causes it?
A.A blue-violet (violet) colour caused by a copper(II) complex with at least two peptide bonds
B.A brick-red precipitate of copper(I) oxide
C.A blue-violet colour caused by free amino groups only
D.A yellow colour caused by elemental sulfur
Explanation: The Biuret test detects peptide bonds: in alkaline solution Cu2+ ions form a violet complex with the nitrogen atoms of at least two peptide bonds. Free amino acids (single amino group, no peptide bond) do not give this reaction; the brick-red Cu2O precipitate belongs to the Fehling test for aldehydes.
10Amino acids such as glycine are colourless solids with melting points above 230 °C that dissolve well in water but poorly in nonpolar solvents. Which structural feature explains these properties?
A.Their zwitterionic structure, which creates strong ion-dipole interactions with water and ionic lattice forces in the solid
B.Their long unbranched hydrocarbon chains
C.Their ability to form extensive hydrogen-bond-free crystal lattices
D.Their aromatic ring systems
Explanation: As Zwitterions, amino acid molecules carry full positive and negative charges. In the solid, strong electrostatic attraction between the ions produces a salt-like lattice with a high melting point; in water, ion-dipole interactions hydrate the ions and make them soluble.
