What causes surface tension under water

Chemistry
1 answer:
RSB [31]3 years ago

In general ethers have a much lower boiling point than their isomeric alcohols. why?
Alex Ar [27]

Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .

Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.

Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.

Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .

if the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat
Alex777 [14]

If the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat is absorbed from the surroundings and the overall mixing process is said to be endothermic process.

The endothermic process can be defined as the process in which the reactants the will absorbed the heat from the surroundings . the heat is gained from the surrounding in the endothermic process and the surroundings temperature will decreases.

The solvent - solute interaction < solute - solvent interaction \and the solute solute interaction then the solution may be or may not be formed.

Thus, then heat is absorbed from the surroundings and the overall mixing process is called as endothermic process.
