Valence electtons 4+1*4=8

Lewis dot structure:


Bonding pairs - 4

lone pairs -0

General formula AB4

Electron geometry - tetrahedral

Molecular geometry - tetrahedral

Bond angle 109.5


Difference in electronegativities oo C and H is 2.5-2.1 =0.4. C-H bonds are nonpolar.

The molecule is nonpolar as bonds are non polar and molecule is symmetrical.
