Question

Which one of the following molecular hydrides acts as a Lewis acid? (A)  NH3 (B) H2O (C) B2H6 (D) CH4

Tardigrade Admin · Accepted Answer

Electron deficient molecules t as Lewis acid. Among the given molecules, only diborane is electron deficient, i.e. does not have complete octet . Thus, it acts as a Lewis acid. NH3 and H2O being electron rich molecules behave as Lewis base.
