What is the major product upon addition of HCl to 1-hexene? A) CH₃CH₂CH₂CH₂CHClCH₂Cl B) CH₃CH₂CH₂CH₂CH₂CH₃ C) CH₃CH₂CH₂CH₂CHClCH₃ D) CH₃CH₂CH₂CH₂CH₂CH₂Cl E) CH₃CH₂CH₂CH₂CHCl=CH₂

Question

Quizplus · Accepted Answer

Upon addition of HCl to 1-hexene, the double bond will undergo electrophilic addition. Specifically, the hydrogen from HCl will add to one carbon, and the chloride will add to the other carbon. This yields a 1-chlorohexane product. Therefore, the correct answer must include a molecule that has a hexyl chain with a chlorine atom. Choices A, B, D, and E all have longer or shorter chains than hexyl or do not have a chlorine atom. Choice C, however, is CH3(CH2)4CH=CH2 + HCl -> CH3(CH2)5Cl, which is the correct product.
