Chemistry - Biomolecules

Practise 24 VITEEE previous year questions on Biomolecules, compiled from papers spanning 2008 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.

Biomolecules has been asked in 12 of the 18 years of VITEEE papers analysed (2006–2024), with 24 questions in all. 38% of them were easy, 50% moderate and 13% tough. Most of its questions came from 2018, with 3 questions that year. In the last three years (2022–2024) it had 2 questions across 1 paper, about 2 per paper.

The chapter's 7 topics are not weighted equally: Carbohydrates (6 questions, 25%), Proteins (5 questions, 21%), and Properties and Preparation of Amino Acids (4 questions, 17%) have been asked the most. Carbohydrates has also led over the last five years, with 1 question. Preparation and Reactions of Glucose has produced the most tough questions (2).
