Which of the main product HOCl reacts on 3-methyl-2-pentene
(a) \(CH_3 - CH=\underset{Cl}{\underset{|}{C}} - CH(OH)-CH_3\)
(b) \(CH_3 -\overset{OH}{\overset{|}{CH}} -\overset{CH_3}{\overset{|}{\underset{Cl}{\underset{|}{C}}}}- CH_2-CH_3\)
(c) \(CH_3 -\overset{Cl}{\overset{|}{CH}} -\overset{CH_3}{\overset{|}{\underset{OH}{\underset{|}{C}}}}- CH_2-CH_3\)
(d) None of these
Correct answer: (c) \(CH_3 -\overset{Cl}{\overset{|}{CH}} -\overset{CH_3}{\overset{|}{\underset{OH}{\underset{|}{C}}}}- CH_2-CH_3\)
Explanation:
The reaction follows Markownikoff rule
\(CH_3CH_2-\overset{CH_3}{\overset{|}{C}} =\overset{H}{\overset{|}{C}}-CH_3 \)+ \(\overset{\delta -}OH \overset{\delta +}Cl\) → \(CH_3CH_2 -\overset{CH_3}{\overset{|}{\underset{OH}{\underset{|}{C}}}}- \overset{H}{\overset{|}{\underset{Cl}{\underset{|}{C}}}}-CH_3\)
