Explanation / Answer

(51) When an unsaturated compound is treated with ozone, it adds on doubly bonded carbon atoms forming carbonyl compound/s.

So,

CH3(CH2)4CH(=O)+O=CHCH2CH=O+O=CH(CH2)7COOH ---->CH3(CH2)4CH=CHCH2CH=CH(CH2)7COOH

So, the unkown fatty acid is Linoleic acid.

(D)

(52)

Fishcer - Kiliyani synthesis is used to increase aldose by one carbon. In this method first aldose is treated with HCN, followed by acidic hydrolysis, removal of excess acid and finally by Na-Hg,H2O

So, (C)

(53) Glyceirdes are the esters of glycerol and fatty acids.

(E) Alcohol and carboxylic acid

(54)

(B) I and III

Anomers are the isomers that differ only in the stereo chemisry of newly created chiral carbon (C1) .
