4. Arrange the following substances in order of increasing boiling point: CH3CH2OH, HOCH2CH2OH, CH3CH2Cl , and ClCH2CH2OH A. CH3
Studentka2010 [4]

Answer: Option (B) is the correct answer.

Explanation:

A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.

So, in the molecule HOCH_{2}CH_{2}OH there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.

In the molecule ClCH_{2}CH_{2}OH there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than HOCH_{2}CH_{2}OH.

In the molecule CH_{3}CH_{2}OH, there will be only hydrogen bonding. Hence, its boiling point is less than ClCH_{2}CH_{2}OH.

In the molecule CH_{3}CH_{2}Cl, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.

Therefore, we can conclude that increasing order of boiling point will be as follows.

        CH_{3}CH_{2}Cl < CH_{3}CH_{2}OH < ClCH_{2}CH_{2}OH < HOCH_{2}CH_{2}OH

Question 2: Naming Hydrocarbons
oksian1 [2.3K]

Answer:

1) 1-Pentyne

2) But-2-yne

3) Ethyne

4) 1-Propyne

5) 1-Butyne

6) Pent-2-yne

Explanation:

1) The number of carbon on the longest chain = 5, (two carbon atoms between the triple bond) therefore the prefix is <em>pen-</em>

The functional group is the triple bond on the first carbon with the suffix <em>-yne</em>

The name of the compound is 1-Pentyne

2) There are 4 carbon atoms on the longest chain, therefore, the prefix is <em>but-</em>

The location of the triple bond functional group (suffix; <em>-yne</em>) is on the second carbon atom

Therefore, the name of the compound is But-2-yne

3) The triple bond functional group is between the only two carbon atoms, therefore, the name is Ethyne

4) The number of carbon atoms = 3, with a prefix <em>prop-</em>, and the functional group on the first carbon atom on the longest chain is the triple bond, with suffix <em>-yne</em>

Therefore, the name of the compound is 1-Propyne

5) The number of carbon atoms on the longest chain = 4, the prefix is <em>but-</em>

The location of the triple bond functional group (suffix<em> -yne</em>) is on the first carbon atom

Therefore, the name is 1-Butyne

6) The number of carbon atoms on the longest chain = 5, the prefix of the compound is <em>pen-</em>

The location of the triple bond functional group (suffix; <em>-yne</em>) is on the second carbon atom, therefore;

The name of the compound is Pent-2-yne
