Question

5. The molecular masses of the following five molecules are all between 100- 104. and will not be a factor in your answers to the questions. Do not look up data; answer the questions using basic principles of intermolecular force strength. For the last three questions, identify all intermolecular forces. and weill og br nases of the folowing five a. CH3CH-CH2C-OH b. CH CHCH2CH2CH2CH3 c. CH3CH-CH-CHCH OH CH3 CH3 d. HO-CH CH CH CH2CH e e. CH,CH,CH,CH,CH,CH,CHs Arrange these molecules in the expected order of increasing vapor pressure. (lowest first) 5. Which of these molecules is expected to have the lowest boiling point? Explain on the basis of intermolecular forces not vapor pressure.

Explanation / Answer

1) e < c < d < a < b

2) e , c

The weak london force plays an role in alcohol solubility, the force which holds liquid,gas and solid at this state are weak. The polarization favours the solubity.

3) a,b,d

The dipole-dipole interaction favours the electron sharing between =O and -CH3 , the order varies based on the postion of =O arrangement (alpha means higher)
