Predict the product C obtained in the following reaction of butyne-1. CH3CH2−C≡CH + HCl → B → C

1. CH3−CH2−CH2−C−H | Cl
2. CH3−CH2−CH−CH2Cl
3. CH3CH2−C−CH3 | Cl
4. CH3−CH−CH2CH2Cl

Correct answer: CH3CH2−C−CH3 | Cl

Solution

The reaction involves the addition of HCl to butyne-1. The Markovnikov rule applies, leading to the formation of 2-chlorobutane as the final product (C).
