Two students are assigned two pure compounds to investigate. They observe that compound A boils at 37°C and compound B at 126°C. However, they run out of time to take any additional measurements, so they make the following guesses about the two compounds. In each case, indicate if the guess can be justified by the data, if it is in error, or if it could be either true or false. Justify your answers.

(a) Compound B has the higher molar mass.

(b) Compound A is the more viscous.

(c) Compound B has stronger intermolecular forces.

(d) Compound B has the higher surface tension.
