JEE Main levelSingle correct optionDifficulty 2 of 3hx078
Phenylmagnesium bromide is treated with ethanal and the product is hydrolysed with HX3OX+. The product is
A1-phenylethanol
Bphenylmethanol
C2-phenylpropan-2-ol
D2-phenylethanol
Answer: A
The phenyl carbanion adds to the carbonyl carbon of CHX3CHO, giving CX6HX5−CH(CHX3)−OMgBr. Hydrolysis yields a secondary alcohol, CX6HX5CH(OH)CHX3, which is 1-phenylethanol.
