Hydrocarbons are nonpolar. Therefore, CH3CH2CH2CH3 is a nonpolar molecular compound and the only intermolecular forces are induced dipole forces. Hydrogen bonding is found in situations represented by D-H—A where both the donor atom, D, and the acceptor atom, A, are one of the highly electronegative elements O, N, or F. Hydrogen bonding is not expected to be important in compounds in which all of the H atoms are covalently bonded to C atoms, even when an acceptor atom is present in the molecule. What type(s) of intermolecular forces are expected between HCOOH molecules?
