A technique used for measuring the molecular weight and determining the molecular formula of an organic molecule is ____________ . A compound that contains an odd number of ____________ atoms gives a molecular ion an odd mass. When the molecular ion consists of two peaks (M and M+2) in a 1:1 ratio, a ____________ atom is present in the molecule. For a bond to absorb in the IR, there must be a change in the dipole moment during the ____________ . Organic chemists use ____________ to identify the functional groups in a compound. When the molecular ion consists of two peaks (M and M+2) in a 3:1 ratio, a ____________ atom is present in the molecule. The higher the percent s-character, the strong the bond, and the ____________ the wavenumber of an IR absorption. Hydrocarbons and compounds that only contain C, H, and O atoms always have a molecular ion with an ____________ mass.
