Question

Which of the following statements regarding alcohols and ethers are true? Add a check by all the true statements. Ethanol is more likely to be a liquid at 50 degree C than is methoxyethane (ethyl methyl ether). Alcohol molecules can form hydrogen bonds among themselves; ether molecules cannot. Methoxyethane (ethyl methyl ether) has a higher boiling point than ethanol. Methoxyethane (ethyl methyl ether) is more soluble in water than is ethanol. Methoxyethane (ethyl methyl ether) is more likely to be a liquid at 50 degree C than is ethanol.

Answer 1

Concepts and reason

Consider the boiling point and properties of alcohols and ether for identifying the true statements.

Fundamentals

Boiling point is defined as the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure. The liquids with higher intermolecular forces have higher boiling point.

The solubility of the compound depends on the type of forces present in the compound. The compounds having hydrogen bonding are soluble in water.

The incorrect statements are as follows:

Methoxyethane (ethyl methyl ether) has a higher boiling point than ethanol.

Methoxyethane (ethyl methyl ether) is more soluble in water than is ethanol.

Methoxyethane (ethyl methyl ether) is more likely to be liquid at than is ethanol.

The correct statements are as follows:

Ethanol is more likely to be liquid at than is methoxyethane (ethyl methyl ether).

Alcohols molecules can form hydrogen bonds among themselves; ether molecules cannot.

Ans:

The true statements are as follows:

Ethanol is more likely to be liquid at than is methoxyethane (ethyl methyl ether).

Alcohols molecules can form hydrogen bonds among themselves; ether molecules cannot.
