Rank the following in terms of increasing boiling point:. CH3CH2OCH2CH3 CH3CH2OCH3 CH3CH2CH2CH3 CH3CH2CH2CH2NH2 a. CH3CH2CH2CH2NH2 < CH3CH2CH2CH3 < CH3CH2OCH3 < CH3CH2OCH2CH3 b. CH3CH2CH2CH3 < CH3CH2OCH2CH3 < CH3CH2OCH3 < CH3CH2CH2CH2NH2 c. CH3CH2OCH3 < CH3CH2CH2CH3 < CH3CH2OCH2CH3 < CH3CH2CH2CH2NH2 d. CH3CH2CH2CH2NH2 < CH3CH2OCH2CH3 < CH3CH2OCH3 < CH3CH2CH2CH3 e. CH3CH2CH2CH3< CH3CH2OCH3< CH3CH2OCH2CH3< CH3CH2CH2CH2NH2

The correct ranking of the given organic compounds from highest to lowest boiling points is given by;

Option D; CH3CH2CH2CH2NH2 < CH3CH2OCH2CH3 < CH3CH2OCH3 < CH3CH2CH2CH3

We are given the organic compounds;

CH3CH2OCH2CH3

CH3CH2OCH3

CH3CH2CH2CH3

CH3CH2CH2CH2NH2

The family names of the given organic compounds are;

CH3CH2OCH2CH3 is an ether

CH3CH2OCH3 is an ether

CH3CH2CH2CH3 is an alkane

CH3CH2CH2CH2NH2 is an amine

The boiling points are given in the order from highest to lowest as;

Alkanes < Ethers < Amines

This is because Amines have higher possibility of hydrogen bonding than the others.

Lastly, a longer chain ether will have a higher boiling point than the shorter chain one because it can have more Vander walls force interactions.

Thus, the correct order of arrangement of the given organic compounds from highest to lowest boiling point is;

CH3CH2CH2CH2NH2 > CH3CH2OCH2CH3 > CH3CH2OCH3 > CH3CH2CH2CH3

Explanation:

Some important factors affect the boiling point of aliphatic compounds. Prominent among them are;

1) relative molecular mass

2) nature of intermolecular

3) surface area of compound.

In this case, the nature of intermolecular forces and the molecular mass of the compounds are worthy of mention.

The degree of dipole interaction in CH3CH2CH2CH2NH2 is far greater than that in the ethers hence the amine has the highest boiling point followed by the ether of higher molecular mass then the ether of lower molecular mass and finally the alkane has the lowest boiling point because only dispersion forces are involved.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
