`B(OH)_(3)` is acidic while `In(OH)_(3)` is basic.
`B_(OH)_(3)` has highly H-bonded network structure.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct reason : Due to small size and high ionisation enthalpy, `B` in `B(OH)_(3)` accepts `overset (Ө) O H` ion from `H_(2) O` and thus acts as a Lewis acid. However, due to large size and low ionisation enthalply of In, the `In-OH` bond readily breaks and releases `overset (Ө) O H` ion, thus `In(OH)_(3)` acts as a base.
