I'm having trouble with this question

Predict the shape of HCN molecule, the hybridization of the orbitals on the carbon atom, and the type(sigma or pi) of each bond

Much thanks

The shape will be Linear

H-C-N

 1 of carbon's valence electrons will be used to form a covalent bond with hydrogen's valence electron

3 of carbon's valence electrons will be used to form 3 covalent bonds with nitrogen'a valence electrons forming a triple bond.

The C is sp hybridized

there's one sigma bond from the H to the C and one from the C to the N, as well as two pi bonds from the C to the N
