(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

The SP2 predicted geometry is trigonal planar and what do you know, formaldehyde is trigonal planar. (ii) HCâ¡N. the bonding between the carbon and the nitrogen in hydrogen cyanide or hydrocyanic acid is a triple bond, hence the hybrid orbital is sp, due to the linear geometry of the molecule. (iii) Ch3CH2CH3.In Propane, the carbon atoms use sp3 hybrid orbitals for the formation of sigma bonds. The single covalent bonds joining carbon to carbon and carbon to hydrogen in alkanes are sigma bonds formed by the end-on overlap of electron orbitals, so that each carbon atom is the center of a tetrahedron.iii) Ch3CH2CH3.
