Problems and exercisesAddition of Organometallic Reagents

1. Products

Which alcohol is obtained in each case, after acid hydrolysis?

1. CH₃MgBr + formaldehyde
2. CH₃CH₂MgBr + ethanal
3. C₆H₅MgBr + acetone
4. CH₃Li + cyclohexanone

2. Two ways

Propose two combinations of a Grignard reagent and a carbonyl compound to prepare 2-pentanol.

3. Conditions

Why are Grignard reagents prepared in dry ether under an inert atmosphere?
