The nucleus of a singly ionized carbon atom contains
-
- 6 protons and 6 neutrons
- 5 protons and 6 neutrons
- 6 protons and 6 neutrons and 6 electrons
- 12 protons and 6 neutrons and 6 electrons
Correct Option: A
The charged carbon atom in a carbocation is a "sextet", i.e. it has only six electrons in its outer valence shell instead of the eight valence electrons that ensures maximum stability (octet rule). Therefore carbocations are often reactive, seeking to fill the octet of valence electrons as well as regain a neutral charge.
