Question

why carbon cannot form four bonds​

Answer 1

$\huge\bold\red{Answer!}$

Required Reason !

The reason a carbon atom cannot bond with four electrons with another carbon is due to the carbon electron orbitals.

Since it has a s and 3 p orbitals, it must create one sigma and at most 2 pi bonds with another carbon.

Hence, you'll have to bond them with another atom.

Carbon Bonding

Because it has four valence electrons, carbon needs four more electrons to fill its outer energy level.

By forming four covalent bonds, carbon shares four pairs of electrons, thus filling its outer energy level.

A carbon atom can form bonds with other carbon atoms or with the atoms of other elements.

Hope it helps...

Answer 2

carbon can form four bond because:--

• carbon have 4 electron in its outermost cell.Carbon need four electron to complete it's octat to stable so it form covalent bond with another element .
• Due to formation of 4 covalent bond carbon have property of catenation (form a long continuous chain ) and are ability to combine with many molecules.

hope it may helps you :-)
