Reaction of CH2=CH2 with RMgX leads to formation of

1. RCHOHR
2. RCHOHCH3
3. RCH2CH2OH
4. RCHCH2OH

Correct answer: RCH2CH2OH

Solution

The reaction of ethene (CH2=CH2) with a Grignard reagent (RMgX) followed by hydrolysis leads to the formation of RCH2CH2OH, as the Grignard reagent adds to the double bond and hydrolysis converts the intermediate to an alcohol.
