Answer 1

Answer:

C₂H₅CH₂CH₂OH is the product.

Explanation:

Grignard reagents are strong nucleophiles with negative charge on alkyl groups.

These grignards react on epoxide quite well.

The grignard attacks the less substituted carbon oxygen bond.

This adds the alkyl group of the grignard with carbon.

The hydrolysis forms the basic magnesium bromide and primary alcohol.

This mechanism goes through the carbanion mechanism.

So the primary alcohol is mostly formed.
