Solution
The relative stabilities of free radicals explained on the basis of hyperconjugation. The number of hyperconjugated structure of a free radical species depends on the alpha-hydrogen atoms present. Greater the number of alpha hydrogens in a given structure, more stable the radical will be.
Thus, relative stability order of free radical is as follows:
Tertiary > Secondary > Primary
Thus, relative stability order of free radical is as follows:
Tertiary > Secondary > Primary
