CBSE Class 12 Chemistry Question Paper Analysis 2026

Set 1, code 56/1/1, moved across Physical, Inorganic and Organic Chemistry instead of keeping one branch in a separate block.

MCQs and assertion-reason questions

Questions 1 to 12 covered reaction order, freezing point, transition metals, electrolysis, aspirin, coordination compounds, phenol, stereochemistry, aniline and vitamins. Questions 13 to 16 used assertion-reason statements on azeotropes, phenol, actinoids and glucose pentaacetate. The one-mark section therefore tested facts, reaction knowledge and short calculations.

Short answers and calculations

Section B included Raoult's law, haloarenes, coordination-compound naming, amino acids and reaction order. Section C moved to longer work such as a first-order decomposition calculation, electrochemistry, boiling-point elevation with benzoic acid, glucose reactions and organic reaction mechanisms.

Case-based and long-answer questions

The two case-based questions focused on amines and coordination compounds. The long-answer section included organic identification and conversion, transition-metal chemistry and an electrochemical-cell calculation using emf and Gibbs energy. These five questions carried 23 marks in total.

The Chemistry syllabus gives the chapter list, while the Class 12 exam pattern covers the common board-paper rules.
