Question

In the three-dimensional structure of methane, CH4, where are the hydrogen atoms attached to a carbon atom aligned?

Answer 1

I hope I address your question.............

Explanation:

`"Methane"` contains `4xxC-H` bonds, with a single carbon atom in the centre of the tetrahedron. Given this geometry, then `/_H-C-H=109.5^@`.

And with tetrahderal geometry, ALL of the hydrogen atoms can be interchanged by a symmetry operation, and thus the hydrogen atoms are EQUIVALENT.
