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?
Composition of methane molecule: Methane molecule consists of one carbon and four hydrogen atoms (CH4). Geometry of methane: Methane molecule is tetrahedral in structure in which carbon is central atom and four H-atoms are surrounding it in three-dimensions. Bond Angles: HCH-bond angles are 109.5o.ue to this property, methane is used as a domestic and industrial fuel. CH4 + 2O2 CO2 + 2H2O HALOGENATION: Replacement of halogen atom with H-atom of an organic compound is called Halogenation. It is a substitution reaction. This reaction occurs in the presence of sun light. It is a free radical mechanism eaction.
