Which order is correct when the following substances are arranged in order of increasing boiling point?
|
|
CH3CH3 < CH3CHO < CH3CH2OH
|
|
|
CH3CHO < CH3CH2OH < CH3CH3
|
|
|
CH3CH2OH < CH3CH3 < CH3CHO
|
|
|
CH3CH3 < CH3CH2OH < CH3CHO
|
Explanation:
Detailed explanation-1: -Thus, the boiling point of CH3CH2OCH2CH3 is higher than that of CH3CH2CH2CH3. CH3CH2OH and H2O have strong intermolecular H-bonds due to the presence of H atoms bonded to electronegative O atoms.
Detailed explanation-2: -Ethanol, CH3CH2OH (mw=46) has a boiling point of 78ยบ.
