Hi there! here's a quick solution for this.

Methoxymethane (dimethyl ether) has a higher boiling point than ethanol.

False (alcohol has greater IMFA since it can form H-bonds so it has a higher BP than ethers)

Methoxymethane (dimethyl ether) is more soluble in water than is ethanol.

False (From the answer in the first question, ether can't do h-bonds with water so ethanol is more soluble than water)

Methoxymethane (dimethyl ether) is more likely to be a liquid at 50°C than is ethanol.

False (ether is likely to be a gas since it has little IMFAs in it)

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

True (-OH group of ethanol can do H-bonds with water)

Ethanol is more likely to be a liquid at 50°C than is methoxymethane (dimethyl ether).

True (since alcohol has greater IMFA it is likely to stay at the liquid phase)
