Question

Due to its sextet (having six electrons), the carbonium ions are:

• A. unstable
• B. very stable
• C. negatively charged
• D. all of these

Answer 1

The correct option is A unstable

As carbon is having 6 electrons and in the outer shell, it is having only 4 electrons so it requires 4 more electrons to complete its octet. so when it occurs in carbonium ion form it is $s{p}^2$ hybridized atom and $s{p}^2$ hybridization with a +ve charge on it make it a very unstable atom.
