Which of the following aldehydes can produce 1o alcohols when treated

1.	Which of the following aldehydes can produce 1o alcohols when treated with Grignard reagent?(a) Methanal(b) Ethanal(c) Propanal(d) ButanalI had been asked this question by my school principal while I was bunking the class.This is a very interesting question from Alcohols and Phenols topic in division Alcohols, Phenols and Ethers of Chemistry – Class 12
Answer» RIGHT choice is (a) Methanal The best I can explain: Methanal on TREATMENT with Grignard reagent forms an adduct which has only one alkyl group attached to the C atom along with TWO hydrogens and one O-Mg-X (X=halogen) group. This on hydrolysis will form a primary alcohol where the OH group will replace the O-Mg-X group.
