(a) The size of B atoms is smaller than that of Al

(b) The sum, IE₁ + IE₂ + IE₃ of B is much higher than that of Al

(c) The sum, IE₁ + IE₂ + IE₃ of Al is much higher than that of B

Both (a) and (b)

H_b..B..H_b bond angle is 118^o

Each boron atom undergoes sp² hybridisation

The boron atoms are linked together through hydrogen bridges

All the atoms lie in the same plane

Its aqueous solution contains equal amounts of weak acid and its salt

It is easily available

Its aqueous solution contains equal amounts of strong acid and its salt

Statement that borax is a buffer, is wrong

Both are Lewis acids, but BCl₃ is stronger

Both are Lewis acids, but AlCl₃ is stronger

Both are equally strong Lewis acids

None of them is a Lewis acid
