Question

For the reaction, $CH _{3}- CH = CH _{2}+ HOCl \rightarrow A$ The product $A$ is :

• A. $CH _{3}- CHCl - CH _{2} OH$
• B. $CH _{3}- \underset{\overset{|}{OH}}{C}H- CH _{2} -Cl$
• C. $CH _{3}- CH_2-CH _{2}- COCl$
• D.

Answer 1

Answer: (B)

For the reaction $CH _{3}- CH = CH _{2}+ HOCl \rightarrow A$
This is addition reaction, this reaction involves in unsaturated compound or that compound which has multiple bonds (= or $\equiv$ bonds)

According to Markownfikoffs rule, the $-ve$ part of reagent is added to that carbon atom of the double bond which bears the least number of hydrogen atom.
