Which of the following will yield a mixture of 2-chlorobutene and 3-chlorobutene on treatment with $$\displaystyle HCl$$?

A$$\displaystyle { CH }_{ 2 }=C=CH={ CH }_{ 3 }$$
Correct Answer
BH2C=C|CH3−CH=CH2
CCH2=CH−CH=CH2
DHC≡C−CH=CH2

Solution

$$\displaystyle { CH }_{ 2 }=C=CH={ CH }_{ 3 }+{ H }^{ + }\longrightarrow \left[ { CH }_{ 2 }=\overset { + }{ C } -{ CH }_{ 2 }{ CH }_{ 3 }+{ CH }_{ 2 }=CH-\overset { + }{ C } HC{ H }_{ 3 } \right] \underrightarrow { { Cl }^{ - } }$$

$${ CH }_{ 2 }=\underset { \underset { \overset { Cl }{ 2-chlorobutene } }{ | } }{ C } { CH }_{ 2 }{ CH }_{ 3 }+{ CH }_{ 2 }=CH-\underset { \underset { \overset { Cl }{ 3-chlorobutene } }{ | } }{ C } HC{ H }_{ 3 }$$
