Which one of the following molecular hydrides acts as a Lewis acid?

Options:

Answer:

Solution:

$B_{2} H_{6}$ is a Lewis acid here as it is electron deficient (6 electron) so it can accept electrons. $N H_{3}, H_{2} O$ are Lewis bases as they have lone pair of electrons to donate. $C H_{4}$ is neither Lewis acid nor Lewis base as it can not donate (have no lone pair) or accept electron (have no vacant orbital).
