Question

The carbon atom in acylium ion formed in Friedal- crafts acylation is hybridized.

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

Answer 1

The correct option is A $sp$

$\mathrm{Structure}\mathrm{of}\mathrm{acylium}\mathrm{ion}\mathrm{is}:R-C\equiv O^{+}\leftrightarrow R-C^{+}=O$
So, the hybridization of carbon atom is $sp$.
