The central atom of a methane molecule is the carbon atom. Four hydrogen atoms are directly bonded to it and there is no lone pairs located in the central atom. Having a tetrahedral shape, every bond angle in methane is equal to 109.5 degrees. Was this answer useful?
It is TETRAHEDRAL about the carbon like methane. However, Unlike methane the tetrahedral shape is NOT symmetric. This is because the oxygen, which combines directly to the carbon is a much larger atom than hydrogen. This distorted tetrahedral shape then has a 'tail' on the oxygen , which is the hydrogen of the alcohol. The bond angles about the carbon are all 109.5 degrees About the carbon the four carbon electrons combine in the following way. Three electrons combine with the three hydrogens in the usual way.
