because of its sp3 hybridised orbital...carbon has tetravalency...and this is why it forms bond with monovalent halogen

why other group members form hexahalides
in which class do u read?
11th
ok then
The electrons in an atom is distributed among various orbitals, namely s, p, d, f. As the elements P and S are from the 3rd period, they have s, p and d orbital. The d orbital remains empty in ground state. When excited, the paired electrons can jump to the d orbital and show an increase ion valency.
hence the elements except carbon....shows valency 6

Carbon forms only tetrahalides it is because it has only 2s and 2p orbitals for hybridisation while other elements like silicon has d-orbitals with 3p and 3s due to which they can have 6 hybridised orbitals and can form hexahalides
