Carbonyl Reaction with Grignard Reagents

In organic chemistry, carbonyl compounds exhibit distinct reactivity patterns due to the polarization of the carbonyl carbon. Consider the following reaction involving a ketone:

Compound A: CH₃COCH₂CH₃ (a ketone) reacts with a nucleophile acting as a Grignard reagent.

What is the major product formed when Compound A is treated with ethylmagnesium bromide (EtMgBr)?
