An alkyl halide by formation of Grignard reagent followed by hydrolysis yields butane. What is the o — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

Hydrolysis of a Grignard reagent ($R-MgX$) directly yields the corresponding alkane ($R-H$) maintaining the exact same number of carbon atoms. To obtain butane ($C_4H_{10}$), the original substrate must be a butyl halide ($C_4H_9X$).
