Answer:
The carbon atom in Chloroform has FOUR bonding pair electrons and ZERO lone pair of electrons.
Explanation:
The carbon atom in Chloroform is bonded to three chlorine atoms and one hydrogen atoms through a single bonds. And the carbon is sp³ hybridized. As we know the electronic configuration of carbons is,
Ground State = 1s², 2s², 2p²
Excited State = 1s², 2s¹, 2px¹,2py¹, 2pz¹
As there are four unpaired electrons in excited state which are all involved in bonding with chlorine atoms and hydrogen atom, therefore, no lone pair of electrons are left.
