1In fact, a B-Cl-B bond may occur in BCl3 as it does in AlCl3, but due to the small size of B, it is not possible.
another reason might be the fulfilled valency of B .
1because B has a small size which cannot accomodate 4 large sized Cl- ion.
24@sankara..
H atoms are small compared to Cl so they can be accomodated ..whereas Cl not
3yeah i know,just give but the actual reason is different that is the bonding is different from other compounds,in BH3 a special type of bonding is there,this type of bonding is in Al(CH3)3 these compounds have a common name called cluster compounds,so the 3c-2e bond doesnt depend on the size of the hydrogen.
