![]() ![]() The two pi bonds between carbon and nitrogen are formed due to the lateral overlap of two p orbitals (may be p x and p y or p x and p z or p y and p z). Thus, sigma bond is much stronger than pi bond. Sigma bond is the outcome of head on overlap of two atomic orbitals and pi bond is formed due to the lateral overlap of two atomic orbitals. Carbon is also bonded with one hydrogen atoms by one sigma bond. Among these three bonds, one is sigma bond and another two is pi bonds. Any covalent bonds is basically consisted of two electrons from each of the bond forming atoms.Ĭarbon is attached with nitrogen atom by three covalent bonds. Central atom is carbon and it is sp hybridized with a linear structure.

Hydrogen participates in the single bond formation with carbon by its one and only valance electrons. Similarly, nitrogen uses its three valance electrons among the five outer most shell electrons to form the triple bond with carbon and rest of the two valance electrons remain as nonbonded electron pair. Valance electron of hydrogen, carbon and nitrogen are 1, 4 and 5 respectively.Ĭentral atom, carbon uses its three valance electrons to form triple bond with nitrogen and last valance electron for the single bond formation with hydrogen atom. ![]() To determine the lewis structure of HCN, valance electrons of carbon, nitrogen and hydrogen should be counted from their electron configuration. Lewis structure or lewis dot structure helps to figure out the valance electrons or hybridization of any compound.
