Current Question (ID: 10895)

Question:

$\text{Electrophilic addition reactions proceed in two steps. The first step involves the addition of an electrophile. The major intermediate formed in the first step is -}$ $\text{H}_3\text{C} - \text{HC} = \text{CH}_2 + \text{H}^+ \rightarrow ?$

Options:

1. $2^\circ \text{ carbanion}$
2. $1^\circ \text{ carbocation}$
3. $2^\circ \text{ carbocation}$ (Correct)
4. $1^\circ \text{ carbanion}$

Solution:

$\text{Hint: Stability of carbocation}$ $\text{When electrophile attacks } \text{CH}_3 - \text{CH} = \text{CH}_2 \text{ delocalisation of electrons can take place, in two possible ways}$ $\text{Carbocation X is } 2^\circ \text{ and carbocation Y is } 1^\circ \text{. As } 2^\circ \text{ carbocation is more stable than } 1^\circ \text{ carbocation. Thus, option third correct.}$
