What will be the boiling point of propanal if the boiling points of methoxyethane and propanol are 281 K and 370 K respectively?
Answer & explanation
Correct answer: option 3
The boiling point of aldehydes are higher than those of non-polar hydrocarbons of comparable molecular masses. However, their boiling points are lower than comparable alcohols, due to the absence of intermolecular hydrogen bonding.
