[bruh]

Hello,
Why does an electrophile with sp² hybridization and one unfilled octet is considered to have an empty "p" orbital, such as in the case with a carbon?
I thought the empty orbital would be another sp² but then that also does not make sense since the hybridization would then be sp³ when bonded to a third atom.

Here is an example where there is a carbon cation as the electrophile and bonds with a generic nucleophile.
Thanks.
