Vedclass · Answer

(C) The reaction involves a Grignard reagent,cyclobutylmagnesium chloride,reacting with cyclobutanol. Grignard reagents are strong bases and react readily with compounds containing active hydrogen atoms (like the hydroxyl group in alcohols). The reaction is an acid-base reaction: $C_4H_7MgCl + C_4H_7OH \rightarrow C_4H_8 + C_4H_7OMgCl$ Here,the cyclobutyl group acts as a base and abstracts the proton from the hydroxyl group of cyclobutanol to form cyclobutane $(C_4H_8)$ as the hydrocarbon product $(P)$.
