A Grignard reagent is formed when magnesium metal and 1-bromopent-2-ene are combined in dry ether. This Grignard reagent produces a mixture of pent-1-ene, cis-pent-2-ene, and trans-pent-2-ene when water is added. Adding water produces the same combination of products in the same ratios when the Grignard reagent is prepared using 3-bromopent-1-ene. Explain this curious result.
