**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.

Furan Benzene H It indicates that electrons in benzene rapidly change their positions corresponding to the two structures. It indicates that there are two independent coexisting forms of benzene. It indicates a chemical equilibrium between the two distinct structures. It indicates that the second structure can be obtained as a mirror image of the first one. It indicates that benzene exists in a single form, which is an average of the two structures.
