Indicate which compound has a higher boiling point and explain why.
a) CO2(l) and CS2(l)
b) CH3CH2OH(l) and HOCH2CH2OH(l)
a) CO2(l) and CS2(l) since it is heavier

Explain your conclusions. a. methyl propanoate, pentanal boiling point b. methyl butanoate, hexanal solubility in water methyl pentanoate, hexanoic acid solubility in water d. methylpropanoate, butanoic acid boiling point
Which compound in each palr nas the higher boing point a CH3CH2CH2CI or CHCH2CH2l b. 'CH3CH2CH2OH or HOCH2CH2OH c CH3CH2CH20H or CH3CH2CH2F 4. 'Explain the following observation. Dimethyl ether [(CH320) and ethanol (CH2CH2OH) are both water-soluble compounds. The boiling point of ethanol (78 C), however, is much higher than the boiling point of dimethyl ether (-24 °C) Dehydration of alcohol C forms two products of molecular formula C14H12 that are isomers, but they are not constitutional isomers. Draw the structures...

If Compound A has a higher boiling point than Compound B, how do their vapor pressures compare? Choose all of the correct answers among: "A is higher than B", "B is higher than A", "A and B are about the same", "depends on the atmospheric pressure", or "depends on their relative molecular weights". Why would distillation not be a good method for separating a mixture of hexane and water? Suggesta better way to separate these two liquids (give the name...
