Least thermally stable is $-$

Least thermally stable is $-$
  1. $\mathrm{CCl}_{4}$
  2. $\mathrm{SiCl}_{4}$
  3. $\mathrm{GeCl}_{4}$
  4. $\mathrm{GeBr}_{4}$

Solution

The thermal stability of tetrahalides decreases in order $\mathrm{CX}_{4}>\mathrm{SiX}_{4}>\mathrm{GeX}_{4}>\mathrm{Sn} \mathrm{X}_{4}$ and in terms of
same metal with different halides is in order
$\mathrm{of} \mathrm{MF}_{4}>\mathrm{MCl}_{4}>\mathrm{MBr}_{4}>\mathrm{MI}_{4}$
