why is( C=H) carbon double bond hydrogen is not possible?
Anamtaaa:
As hydrogen has a valency of 1, it needs 1 more electron to complete its K shell. So it is not possible for hydrogen to make double bond as it just need 1 more electron but double bond would peovide it 2 electrons, resulting in 3 electron in hydrogen which will make it unstable.

C-H bonds are considered nonpolar because carbon and hydrogen have very similar electronegativity values. Also, and not coincidentally, because hydrocarbons as a class are almost entirely non-polar, as shown by their bulk behavior.

Because hydrogen has only one electron and therefore it can form only one bond with carbon
