Question

For a given type of compound (alkane, ketone, or alcohol): a. How does the boiling point change as the molecular mass of the compound increases? b. How do the intermolecular forces between molecules change as the molecular mass increases? c. Find an alkane, ketone, and alcohol with roughly the same molecular mass (within 5 g/mole). Rank these compounds in terms of relative boiling points. d. Using grammatically correct English sentences, describe any general pattern that you can identify about the relative boiling points of alkanes, ketones, and alcohols of roughly equivalent molecular mass.

Explanation / Answer

a ) molar mass increases boiling point also increases. molar mass increases there will be greater number of attraction forces exist among molecules . so boiling point increases

b) molar mass increases intermolecular forces also increases. there will be more forces possible for each added atom or group of atoms

c) C3H8 alkane

     CH3COCH3 ketone

    CH3CH2CH2OH alcohol

boiling points order : alcohol > ketone > alkane

CH3CH2CH2OH   > CH3COCH3 > CH3CH2CH3

d)

alcohol > ketone > alkane

in alcohol there will H-bonds possible they have higher BP
