Question

Match the words to the appropriate blanks in the sentences.

a. For the pair of compounds CO2 or NO2 the one with the highest boiling point is __________ .
b. For the pair of compounds NH3 or CH4 the one with the highest boiling point is _________
c. For the pair of compounds CS2 or CO2 the one with the highest boiling point is _________
1. CH4
2. NH3
3. CS2
4. NO2
5. CO2

Answer 1

a. NO2

b. NH3

c. CO2

Step-by-step explanation:

a. For the pair of compounds CO2 or NO2 the one with the highest boiling point is __________ .

The answer is NO2. It has a higher boiling point than CO2 because it exhibits dipole-dipole interactions.

b. For the pair of compounds NH3 or CH4 the one with the highest boiling point is _________

NH3 has a higher boiling point compared to CH4. This is due to the presence of the hydrogen bonds in NH3,

c. For the pair of compounds CS2 or CO2 the one with the highest boiling point is _________

CS2 has a higher boiling point than CO2. This is because of the high molecular mass of CS2.
