Question

name the shapes of methane and carbon dioxide molecules​

Answer 1

Answer:

name of methane shape

Tetrahedral

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.

name of carbon dioxide

linear

Carbon dioxide has two electron groups and no lone pairs. Carbon dioxide is therefore linear in electron-group geometry and in molecular geometry. The shape of CO2 is linear because there are no lone pairs affecting the orientation of the molecule.
