A resident expert on electronegativity comes up to visit with you. He makes two claims (seen below) about electronegativity with relation to covalent bonding. Is the expert correct or can you refute him with your knowledge of electronegativity? (a) If a diatomic molecule is made up of atoms X and Y, which have different electronegativities, the molecule must be polar. (b) The farther two atoms are apart in a bond, the larger the dipole moment will be.

Rank the bonds in each set in order of decreasing bond length and decreasing bond strength: (a) Si-F, Si-C, Si-O; (b) N=N, N-N, N=N.
