Question

The carbocation formed in $S_{N}1$ reaction of alkyl halide in the slow step is:

• A. $s{p}^3$ -hybridised
• B. $s{p}^2$ -hybridised
• C. $sp$ -hybridised
• D. $s{p}^{3}d$ - hybridised

Answer 1

Answer: (B)

In $S{N}_1$ reaction, the carbocation formation is a slow step. The carbocation formed is a planar, species containing $s{p}^2$ -hybridised carbon atom, electron deficient and an empty $p$-orbital.
