Which of the following linear chain alcohols is likely to have the highest stand

Question

Which of the following linear chain alcohols is likely to have the highest standard entropy in the liquid state? Why? CH_3OH CH_3CH_2OH CH_3CH_2CH_2OH CH_3CH_2CH_2CH_2OH CH_3CH_2CH_2CH_2CH_2OH At what temperature (in Kelvin units) is the entropy of a pure crystal 0.0 J/K. Consider the boiling of a pure liquid at constant pressure. Is each of the following greater than zero, less than zero or equal to zero. For the following changes, estimate the signs (positive, negative, or 0) of deltaS and deltaG. The growth of a crystal from a supersaturated solution.
