Question 1:
Question 2
Arrange the following substances in order of increasing boiling point: A) CH3CH2OH B) CH3CH2CH3 C) CBr3CBr2CBr3 D) CH3OCH3
Question 3
Rank The Following Compounds In Order Of Increasing Boiling Point
Answer question 1
alkanes have lower boiling point than alcohol and
compared to isomers of alkane branched chain alkanes have lower boiling point than straight chain isomer it might be bbranched isomer has lower surface area hence intermolecular forces become weak.
therefore increasing order is
C<E<A<B<D
Answer question 2
The increasing order of boiling point is as follows:
CH3CH2CH3<CH3OCH3<CBr3CBr2CBr3<CH3CH2OHCH3CH2CH3<CH3OCH3<CBr3CBr2CBr3<CH3CH2OH
Ethanol has the highest boiling point as it exhibits strong hydrogen bonding, while the rest of the molecules have only London dispersion forces. Propane has the lowest boiling point as it has the lowest molecular mass. The increase in masses of the compounds increases the number of electrons present that can produce London dispersion forces making for stronger attraction, but they cannot compete with the hydrogen-bonding forces in ethanol in this group of compounds.
