Question

Select correct statement about carbonium ion $\stackrel{\oplus }{C}{H}_3$ :

• A. It is planar with empty $p$-orbital
• B. There are three sigma $\left(CH\right)$ bonds
• C. It is electron deficient with six electron in outer-shell
• D. All of the above

Answer 1

The correct option is D All of the above

Carbon has 4 electrons in it's outer shell but positive charge on carbon which means it has given one electron from it's outer shell and remaining three electron of carbon form three covalent bond with hydrogen

Hence it $s{p}^2$ hybridized which is planar and As it has positive charge which means it has one vacant p orbital.

Hence, the correct option is D.
