How can you explain higher stability of BCl-3 as compared to TlCl-3-

Question

Toppr Admin · Accepted Answer

B shows -3 oxidation state and can form stable BCl3- Thallium shows -1 and -3 oxidation state- Due to inert pair effect- -1 oxidation state is more stable than -3 oxidation state- Hence- BCl3 is stable but TlCl3 not-

How can you explain higher stability of $B C l_{3}$ as compared to $T l C l_{3}$ ?

B shows +3 oxidation state and can form stable $B C l_{3}$ . Thallium shows +1 and +3 oxidation state. Due to inert pair effect, +1 oxidation state is more stable than +3 oxidation state. Hence, $B C l_{3}$ is stable but $T l C l_{3}$ not.
