Alcohols and Ethers - Result Question 42
47. Cyclobutylbromide on treatment with magnesium in dry ether forms an organometallic compound $(A)$. The organometallic reacts with ethanal to give an alcohol $(B)$ after mild acidification. Prolonged treatment of alcohol $(B)$ with an equivalent amount of $HBr$ gives 1-bromo-1methylcyclopentane $(C)$. Write the structures of $(A),(B)$ and explain how $(C)$ is obtained from $(B)$.
