Vedclass · Answer

(B) The reaction of $MeMgBr$ (a Grignard reagent) with hydrocarbons occurs if the hydrocarbon has an acidic hydrogen atom. $MeMgBr$ acts as a base and abstracts the most acidic proton to form methane $(CH_4)$.Among the given options,$1,3$-cyclopentadiene contains a methylene group $(-CH_2-)$ between two double bonds. The hydrogen atoms on this carbon are significantly more acidic than those in other hydrocarbons because the resulting cyclopentadienyl anion is aromatic ($6\pi$ electrons,$H$ückel's rule),which provides high stability.Therefore,$1,3$-cyclopentadiene reacts readily with $MeMgBr$ to form methane and the cyclopentadienyl Grignard reagent.

Which of the following hydrocarbons reacts easily with $MeMgBr$ to give methane?
