Direction (Q, Nos. 1 - 5) This section contains 5 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONLY ONE option is correct.

Q. Which molecule will give the following dicarboxylic acid upon treatment with acidic solution of KMnO₄?

Propose major product of the following reaction.

An  optically active alky bromide X (C₆H₁₃Br) upon treatment with ethanolic KOH solution forms two alkenes Y and Z with their molecular formula (C₆H₁₂). Y and Z are positional isomers. Z upon treatment with cold, dilute alkaline KMnO₄ solution gives a meso-diol. Hence, X is

Which starting material should be used to produce the compound shown below?

When reacted with an alkene, which of the following reagent would not introduce I atleast one hydroxyl (— OH) group into final product?

Direction (Q. Nos. 6 and 7) This section is based on Statement I and Statement II. Select the correct answer from the codes given below.

Statement I :  In reductive ozonolysis, dimethylsulphide is better reducing reagent than Zn- H₂O.
Statement II : (CH₃)₂S brings about homogeneous catalysis.

Statement I :  cis-2-butene with cold, dilute, alkaline KMnO₄ gives meso-2,3- butanediol.
Statement II :  In alkaline solution, under cold condition, KMnO₄ acts as a mild oxidising agent.
