P- cresol react with chloroform in alkaline medium to give compound `(A)` which adds `HCN` to form `(B)`. The latter on acidic hydrolysis given chiral carboxylie acid. The structure of carboxylic acid is :

p-cresol reacts with chloroform in alkaline medium to give the compound A which adds hydrogen cyanide to form, the compound B. the latter on acidic hydrolysis gives chiral caboxylic acid. The structure of the carboxylic acid is
