Question

Which of the following is not tetrahedral in shape
1) CH4
2)C2Cl6
3) NH3
4) Diamond​

Answer 1

Answer:

NH3

Explanation:

NH3 has 5 valence electron in nitrogen atom and no. of sigma bond is 3 so , n = 5-3/2 = 4 but there is one lone pair and due to this lone pair the shape is not tetrahedral but since geometry depends in hibridization therefore geometry will be tetrahedral
