Cyclopentyl bromide on treatment with ma...

Cyclopentyl bromide on treatment with magnesium in dry ether forms an organometallic compound (A). The organometallic compound reacts with ethanal to give an alcohol (B) after mild hydrolysis. Prolonged treatment of alcohol (B) with an equivalent amount of HBr gives 1-bromo-1- methylcyclohexane (C). Write the structure of (A), (B) and explain how (C) is obtained from (B)?
