(a)
Which halogen compound in the following pair will react faster in $\displaystyle \mathrm{S}_{\mathrm{N}} 1$ reaction and why ?
or
(b) Why is the dipole moment of chlorobenzene lower than that of cyclohexyl chloride ?
Marking-scheme solution
(a)
Due to stability of tertiary carbocation/due to stable
(b)
Due to \(\displaystyle \mathrm{C}-\mathrm{Cl}\) bond in chlorobenzene is \(\displaystyle \mathrm{sp}^{2}\) hybridised whereas in cyclohexyl chloride \(\displaystyle \mathrm{C}-\mathrm{Cl}\) bond is \(\displaystyle \mathrm{sp}^{3}\) hybridised .
