NH3 is distinctly basic while BiH3 is feebly basic. Nitrogen has a small size due to which the lone pair of electrons is concentrated in a small region. This means that the charge density per unit volume is high. ... Hence, the electron donating capacity of group 15 element hydrides decreases on moving down the group.
Is BiH3 acidic or basic?
Explain why NH3 is basic while BiH3 is only feebly basic.
Why NH3 is basic while PH3 is feebly basic in nature?
Explain why is NH_(3) basic while PH_(3)is feebly basic in nature. Both ⋅⋅NH3 and ⋅⋅PH3 are Lewis bases due to the presence of lone electorn pair on the central atom. ... This means that electron releasing tendency of ammonia is also more and is therefore, a stronger base than phosphine.
