Question
Please explain why? Select the best answer and mark the corresponding letter on the scantron. Consult the Instructor If the question has an error. Which of the substances would exhibit the highest Boiling Point? Which of the substances has a dipole but, doesn't have a hydrogen bond accepting group. Which of the substances would exhibit the lowest surface tension? Which of the substances would exhibit the highest vapor pressure? Which of the substances would exhibit the 2nd highest Boiling Point? Which substance would exhibit the 2nd lowest Melting Point Describe ALL of the intermolecular forces that would contribute to the BP of molecule E. H bonding Dipole Dispersion both B and C Which substance would exhibit the highest intermolecular forces? If "like dissolves like", which material is most likely to be able dissolve butane (the molecule shown below)?Explanation / Answer
1. C
among the molecule NH2 group form three hydrogen bonds . So it has high boiling point.
2.E
C=O grop is more dipole compare to OH and NH2 groups. Ketone does not form hydrogen bonds.
3. D
it has small surface area .So it has less boliling point and less surface tension.
4. D
it has lower boinling point. So higher vapour pressure.
5. A
due to inter molecular hydrogen bonds
6. B
2nd lower molecular weight compound. Molecular weight is increases melting point is increases.
7. D
8. C it has form three intermolecular hydrogen bonds
9. B
non polar compounds are soluble in non polar solvents
