(a) Which one of the following pairs of substances undergoes S_N 1 reaction faster and why? CH_3- CH_2- CH_2- Cl OR CH_2= CH - CH_2- Cl (b) Write the…
(a)
Which one of the following pairs of substances undergoes $\displaystyle \mathrm{S}_{\mathrm{N}} 1$ reaction faster and why? \[\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{Cl} \quad \mathrm{OR} \quad \mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{Cl} \]
(b)
Write the major product in the following :
Marking-scheme solution
(a)
\(\displaystyle \mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{Cl}\) because \(\displaystyle \mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}^{\oplus}\) is resonance stabilized. (b)
