Statement-II : In water, orthoboric acid acts as a proton donor.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is Not a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

C

Explanation

Orthoboric acid acts as lewis-acid in water, not as proton donor (as it does not liberate `H^(+)` ion) because it completes its octet by accepting the `OH^(-)` from water.
`B(OH)_(3)+H_(2)O to [B(OH)_(4)]^(-)+H^(+)`
