11.2 How can you explain higher stability of as compared to
?
Both boron and Thallium belong to the 13th group of the periodic table. We know that the stability of lower oxidation state (+1) is increases down the group. Thus is more stable than
. It is due to the +3 of Boron is more stable than +3 of Thallium.
is highly oxidising in nature it reverts back to its +1 oxidation state by gaining an electron.
