Which of the following is true for carbocations?
It has a positive charged carbon.
It has a carbon atom bearing six valence electrons
As the name suggests,
Carbocation ⇒ Carbon + Cation (Positive charge)
An organic species which has a carbon atom bearing six electrons in its outermost orbit and has a positive charge is called a carbocation.
How six electrons?
→ Carbon completes its octet by bonding covalently. But here carbon has positive charge, so six electrons (3 of carbon and 3 of bonded atom)
