(a)
Interpretation:
Easiest hydrogen to remove by the chlorine radical should be identified.
Concept introduction:
Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical
Bond strength is depends on the formation of the radical, if the radical is involving in resonance which weakest bond strength.
(b)
Interpretation:
The secondary hydrogen should be identified.
Radical or free radical:
Unpaired valence electron of an atom, molecule, or ion is called as radical
Bond strength is depends on the formation of the radical, if the radical is involving in resonance which weakest bond strength.
