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?
A carbonâcarbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.The carbonâcarbon single bond is a sigma bond and is formed between one hybridized orbital from each of the carbon atoms.In ethane, the orbitals are sp 3 hybridized orbitals, but single bonds formed between carbon atoms with other hybridisations do occur (e.g. sp 2 to sp 2).n fact, the carbon atoms in the single bond need not be of the same hybridisation. Carbon atoms can also form double bonds in compounds called alkenes or triple bonds in compounds called alkynes. A double bond is formed with an sp 2 hybridized orbital and a p-orbital that isn't involved in the hybridization.
