**Question 4** Consider the bond dissociation energies listed below in kcal/mol: - CH₃-Br: 70 - CH₃CH₂-Br: 68 - (CH₃)₂CH-Br: 68 - (CH₃)₃C-Br: 65 These data show that the carbon-bromine bond is *weakest* when bromine is bound to a _________. - ⃝ tertiary carbon - ⃝ quaternary carbon - ⃝ methyl carbon - ⃝ secondary carbon - ⃝ primary carbon **Explanation:** This question evaluates the understanding of bond dissociation energies with different types of carbons. The bond between bromine and the attached carbon is weakest with the lowest energy value (65 kcal/mol) when bromine is bound to a tertiary carbon, as in (CH₃)₃C-Br.
