Assertion : The H-bond present in NH_(3) dissolved in water is best represented by : H-underset(|)underset(H)(N)-H--underset(|)underset(H)(O)-H and not by H-underset(|)underset(H)overset(|)overset(H)(N)---underset(|)underset(H)(H)-O Reason : The O-H bond polarity is more compared to that N-H bond.

Answer»

If ASSERTION is true but the reason is FALSE
If assertion is false but reason is true
If both assertion and reason are true and the reason is the correct explanation of assertion
If both assertion and reason are true and the reason is not the correct explanation of assertion

Solution :The correct representation of hydrogen bonding is `H-overset(H)overset(|)underset(H)underset(|)(N)….H-underset(H)underset(|)(O)` and AMMONIA never acts as acid in aqueous MEDIUM
`NH_(3)+H_(2)O to NH_(2)^(-)+H_(3)O^(+)`
