In acrylonitrile C3H3N , there is a carbon-carbon single bond C-C and a carbon-nitrogen double bond C=N . To predict the bond strength, we can consider the bond length and electronegativity values of the atoms involved.1. Bond Length:The bond length is the distance between the nuclei of two bonded atoms. Generally, shorter bond lengths correspond to stronger bonds.- Carbon-Carbon single bond C-C : The average bond length of a C-C single bond is approximately 1.54 angstroms .- Carbon-Nitrogen double bond C=N : The average bond length of a C=N double bond is approximately 1.27 .Since the C=N bond is shorter than the C-C bond, it is expected to be stronger.2. Electronegativity:Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Bonds between atoms with similar electronegativity values are generally stronger.- Carbon C : The electronegativity value of carbon is 2.55.- Nitrogen N : The electronegativity value of nitrogen is 3.04.The difference in electronegativity between carbon and nitrogen EN = 3.04 - 2.55 = 0.49 indicates that the C=N bond has some polar character, which can contribute to its bond strength. The C-C bond, on the other hand, is nonpolar since both carbon atoms have the same electronegativity.In conclusion, based on the bond length and electronegativity values, the carbon-nitrogen double bond C=N in acrylonitrile is predicted to be stronger than the carbon-carbon single bond C-C . The shorter bond length and the polar character of the C=N bond contribute to its higher bond strength compared to the C-C bond.
