Answer» Strength as LEWIS acid`-BCl_(3)gtAlCl_(3)gtGaCl_(3)` Inert pair effect-`AlgtGagtIn` Oxidising property-`Al^(3+)gtIn^(3+)gtTi^(3+)` FIRST ionisation ENTHALPY-`BgtAlgtTI` Solution :(a) The tendency to behave as Lewisacid DECREASES with the increases in the size down the group. `BCl_(3)` easily accepts a lone pair of ELECTRONS from ammonia to form `BCl_(3)cdotNH_(3)`. Hence, strength as Lewis acid `BCL_(3)gtAlCl_(3)gtGaCl_(3)`
