Answer» NH3 has a pyramidal shape. Here, the central atom N (nitrogen) has 3 bond pairs and one lone pair. Hence, it is sp3 hybridised. It will have a tetrahedron shape but one of its ends will be occupied by a lone pair which does not contribute to the structure. Therefore, it looks like a pyramid. Also, it will have a bond angle less than that of what a tetrahedron has. This is because the lone pair repels all the bond pairs this results in the reduction of bond angle.

Answer»

NH3 has a pyramidal shape. Here, the central atom N (nitrogen) has 3 bond pairs and one lone pair. Hence, it is sp3 hybridised.

It will have a tetrahedron shape but one of its ends will be occupied by a lone pair which does not contribute to the structure. Therefore, it looks like a pyramid.

Also, it will have a bond angle less than that of what a tetrahedron has. This is because the lone pair repels all the bond pairs this results in the reduction of bond angle.
