For the following radicals, the correct order of their stability is

For the following radicals, the correct order of their stability is
  1. $[\mathrm{A}] < [\mathrm{B}] < [\mathrm{C}] < [\mathrm{D}]$
  2. $[\mathrm{D}] < [\mathrm{C}] < [\mathrm{B}]>[\mathrm{A}]$
  3. $[\mathrm{B}] < [\mathrm{C}] < [\mathrm{D}] < [\mathrm{A}]$
  4. $[\mathrm{B}] < [\mathrm{C}] < [\mathrm{A}] < [\mathrm{D}]$

Solution


More the $\propto \mathrm{H}$, more will be its stability of free radicals. So, the correct order is $[\mathrm{B}] < [\mathrm{C}] < [\mathrm{D}] < [\mathrm{A}]$. .
