For the following radicals, the correct order of their stability is
1 A $<$ B $<$ C $<$ D
2 D $<$ C $<$ B $<$ A
3 B $<$ C $<$ D $<$ A
4 B $<$ C $<$ A $<$ D
Explanation:
The stability of radical is directly proportional to the number of $\alpha-\mathrm{H}$ of the radical. So, the order of stability is - $\mathrm{B}<\mathrm{C}<\mathrm{D}<\mathrm{A}$
