TYPED PLEASE

Why do Hydrogen atoms form only single bonds with other atoms and not double or triple bonds like Carbon atoms?

Answer 1

ans)

from above information that

We know that

Electronic configuration of hydrogen atom -------->1S^1

when only one pair of electron is shared single covalent bond results

since H atom don't have more then one electron

so it has single bond only it can not form double and triple bond

c in ground state of configuration 1s^2 2s^2 2p^2======>1s 2s 2p

in exicted state it has 2s2p configuration

so here total four electrons in valence shell obtained

since carbon has more then one electron in valance shell.so it can form double and triple bond also

so this way hydrogen atoms forms only single bonds compare with the crabon atoms
