Answer 1

Answer:

Hey mate here is your answer ✌️✌️✌️

1. There are less extensive hydrogen bonding between ethanol molecules than between water molecules, thus less energy is needed to vaporise ethanol than water and water has a higher boiling point than ethanol.

Experiment : To find out why there are less extensive hydrogen bonding between ethanol molecules than between water molecules, try drawing out the hydrogen bonding in both molecules. You can see that on average water molecules can form twice as much hydrogen bonding than ethanol molecules because water has two hydrogen atoms that are connected to the electronegative oxygen atom whereas ethanol only has one such hydrogen.

2. Hydrogen bonding increase the boiling point as here required separation energy is more. In case of ethanol OH is the last so one hydrogen is attached with a very electronegative atom (oxygen) directly. So both oxygen and hydrogen become polar. So hydrogen bonding is possible here, which increase the boiling point of ethanol. In case of dimethyl ether oxygen is not directly attached with the hydrogen so hydrogen bonding is not possible so its boiling point is less than ethanol.

Hope it helps you please mark it as brainliest and follow me ❤️❤️❤️

Answer 2

Explanation:

Because hydrogen bonds are typically much stronger attractions than ordinary dipole moments, a group of ethanol molecules is much harder to separate from each other than a group of dimethyl ether molecules. The ethanol has a much higher boiling point.
