Question

In the three-dimensional structure of methane, CH4, the hydrogen atoms attached to a carbon atom are aligned at ____________.

Answer 1

Corner of tetrahedral structure

Step-by-step explanation:

In three dimension methane
`CH_4` has tetrahedral structure in which central atom is carbon which has four valance electron.

Each valence electron of carbon is shared by hydrogen atom as there are 4 valence electron in
`CH_4` so there will be 4 hydrogen atom

And each hydrogen atom is aligned at the corner of tetrahedral structure of
`CH_4`
