Methane is an organic compound that is the primary component of natural gas. … Tetrahedral structure of methane. The molecular geometry of the methane molecule is tetrahedral (see Figure 7). The H-C-H bond angles are 109.5°, which is larger than the 90° that they would be if the molecule was planar.

What is the structure of methane planar?

Most organic molecules, including all alkanes, are not planar but are instead characterized by three-dimensional structures. Methane, for example, has the shape of a regular tetrahedron with carbon at the centre and a hydrogen atom at each corner.

How is methane tetrahedral?

Methane is an example of tetrahedral electron pair geometry . The carbon has 4 valence electrons and needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms are as far apart as possible at 109 degree bond angles. The molecule is three dimensional.

Methane is a molecule with a carbon central atom and four hydrogen atoms attached to it. Complete step-by-step answer: But in methane, there is no involvement of d-orbitals as it has less electrons. So, it cannot have square planar geometry.
