Answer:
Corner of tetrahedral structure
Explanation:
In three dimension methane [tex]CH_4[/tex] 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 [tex]CH_4[/tex] so there will be 4 hydrogen atom
And each hydrogen atom is aligned at the corner of tetrahedral structure of [tex]CH_4[/tex]
