Which is correct statement reagarding `BOH` ( where `chi` is electronegate) ?

Options

A. If `chi_(O)-chi_(B) gt chi_(O)-chi_(H)` will be basic.
B. If `chi_(O)-chi_(B)lt chi_(O)-chi_(H)` will be acidic
C. If `chi_(O)-chi_(B) gt chi_(O)-chi_(H)` will be acidic.
D. If `chi_(O)-chi_(B) lt chi_(O)-chi_(H)` will be basic

Answer

A, B

Explanation

a. If `chi_(O)-chi_(B) gt chi_(O)-chi_(H)`, compound `BOH` will be basic, then `B-O` bond will be more polar than `O-H` bond and hence ionisation of `BOH` molecule in aqueous solution will take place at `B-O` bond and `overset(ɵ)(O)H` will be formed.

b. If `chi_(O)-chi_(B) lt chi_(O)-chi_(H)`, compound `BOH` will be acidic, then `O-H` bond will be more than polar than `B-O` bond and hence ionisation of `BOH` molecule in aqueous solution will take place at `O-H` bond and `H_(3)O^(o+)` ions will be formed.
