Question:
How can you explain higher stability of BCl₃ as compared to TlCl₃?

Answer:

Boron and thallium belong to group 13 of the periodic table. In this group, the +1 oxidation state becomes more stable on moving down the group. BCl₃ is more stable than TlCl₃ because the +3 oxidation state of B is more stable than the +3 oxidation state of Tl. In Tl, the +3 state is highly oxidising and it reverts back to more stable +1 state.
