Vedclass · Answer

(A) No-bond resonance is another term for hyperconjugation.Hyperconjugation occurs in species having $\alpha$-hydrogen atoms attached to an $sp^2$ hybridized carbon atom (such as in carbocations,free radicals,or alkenes).$1$. $CH_3 CH_2^{(+)}$ (Ethyl carbocation): It has three $\alpha$-hydrogen atoms on the adjacent carbon,so it exhibits hyperconjugation (no-bond resonance).$2$. $CH_3 CH_2 Br$: This is an alkyl halide and does not possess the necessary electronic structure for hyperconjugation.$3$. $CH_3 CH_2 NO_2$: This molecule does not exhibit hyperconjugation.$4$. $C_6 H_6$ (Benzene): It exhibits resonance,but not hyperconjugation.However,in the context of standard chemistry problems,$CH_3 CH_2 Br$ is the most appropriate choice as it is a saturated alkane derivative lacking the $\alpha$-hydrogen requirement for hyperconjugation.

Identify the species from the following that exhibits no-bond resonance.
