Shape and hybridisation of NH3 is
pyramidal and sp3
pyramidal and sp2
triangular planar and sp3
triangular planar and sp2
As we learnt ,
Structure of Ammonia -
N atom is sp3 hybridized with lone pair of electrons. It has a pyramidal shape.
Hybridisation sp3
Shape pyramidal
Bond angle 107o
Therefore, option (1) is correct.
