Concept Introduction:
Molecules that have uneven electrons distributed among the bonded atoms are termed as polar molecules. In polar molecules, bonded atoms have difference in their electronegativity.
Polarity of the molecule depends on the dipole moment. Dipole moment is directly related to bond length and bond length depends upon the electronegativity of the atom. Therefore, atom with more electronegativity attracts electrons towards it that in turn shortens the bond length of the molecule. With decrease in bond length, dipole moment of the molecule decreases. As dipole moment decreases, molecule becomes less polar. Therefore, as electronegativity increases, polarity of the molecule decreases.

- H2S and C12CCH2 polar or nonpolararrow_forwardClassify each of the following molecules as polar or nonpolar. H2O2, CF4, N2H2, NO2arrow_forwardChemistry 1. Glycerol, CH2(OH)CH(OH)CH2OH, has a 3 carbon chain with -OH groups coming off of each carbon. This thick, syrup like liquid is used in anti-freeze and as a food additive. Hexaoctane, C18H38, is a greasy wax-like solid at room temperature. Using this information rank molecules in order of increasing boiling point and justify your answer: PCl2F, H2O, SeS3, MgS, Glycerol, CH4, CaS, PF2Cl, Hexaoctane, Nearrow_forward
