Apart from tertrahedral geometry ,another possible geometry for CH4 is square planar with the four H atoms at the corners of square and C atom at its centre. Explain why CH4 is not square planar.

Description : Apart from tertrahedral geometry ,another possible geometry for CH4 is square planar with the four H atoms at the corners of square and C atom at its centre. Explain why CH4 is not square planar.

Last Answer : Ans. In square planar geometry , the bond angle will be 90 ° which is less than bond angle in tetrahedral geometry ( 109.5 °).Therefore repulsive forces in square planar will be more and it will be less stable as compared to tetrahedral geometry.
