NEET levelSingle correct optionDifficulty 1 of 3ap167

Ethylmagnesium bromide, $C X_{2} H X_{5} MgBr$ , is allowed to react with methanal (HCHO) and the adduct is then hydrolysed with $H X_{3} O X^{+}$ . The alcohol formed is

Apropan-1-ol
Bpropan-2-ol
Cbutan-2-ol
D2-methylpropan-2-ol

Answer: A

Grignard reagents add to methanal to give primary alcohols with one more carbon than the Grignard alkyl group.

C X_{2} H X_{5}

plus the carbon of HCHO gives

CH X_{3} CH X_{2} CH X_{2} OH

, propan-1-ol.
