Table: Boiling point relationships for members of the normal alkane series. Here n is the number of carbon atoms in the molecule, t is the boiling point of the n-th member, A t the difference in boiling point temperature between the n-th and (n -|- l)-th member of the series, D is density, and a, fi, and 7 are constants.
