The angle between two of carbon-hydrogen bonds in the methane ( ) molecule is 109.50°
What is the bond angle in a methane molecule?
VSEPR theory predicts methane is a perfect tetrahedron with all H-C-H bond angles equal at 109.50°, because the hydrogen atoms repel equally, and because this geometry puts the greatest distance between all four bonded electrons pairs.
(see attachment)
The VSEPR theory is used to predict the shape of the molecules from the electron pairs that surround the central atoms of the molecule.
The bond angle between carbon-hydrogen bonds turns out to be 109.5 degrees. And it's the same all the way around. So you could say that this angle is 109.5 degrees.
