Question

Which of the following is an incorrect match ?

• A. $Si{F}_4$ : Can act as Lewis acid.
• B. Benzyne : All $C$ - atoms are $s{p}^2$-hybridized.
• C. $PB{r}_3$ : Nonpolar
• D. $CHF=C=CHF$ : Nodal planes of $\pi$-bonds are not lying in the same plane

Answer 1

The correct option is C $PB{r}_3$ : Nonpolar

(c) $Si{F}_4\to Si$ has vacant d-orbital and so can act as Lewis acid.
