Increasing boiling point order for ethanol, chloroform,ethene
Answers
Answer:
The correct order is ethene < chloroethene < ethanol
Explanation:
Ethanol being an alcohol will have the highest boiling point because hydrogen bonds exist between alcohol molecules. More heat is required to overcome the forces of attraction resulting from these hydrogen bonds.
Chloroethane has a higher boiling point than ethane because it has a Cl group. Chlorine is highly electronegative, making the chloroethane molecule polar in nature. The forces of attraction are higher among polar molecules and so, more heat is required to overcome the forces of attraction. Therefore, chloroethane, which is polar, has a higher boiling point than ethane, which is non-polar.
Thus the correct order of boiling point is:
Ethane < Chloroethane < Ethanol
