Explanation

Question 2 of 12

1

Select from the dropdown lists to complete the text.

The boiling points of alcohols increases as the chain length ( increases, decreases ) because there are ( more, fewer ) surface area contacts and stronger ( induced dipole-dipole, permanent dipole-dipole, permanent dipole-induced dipole ) interactions (London forces). Hydrogen bonds also increase the intermolecular force of attraction. The higher the forces of attraction the ( more, less ) energy needed to break the bonds.

Which of these statements about alcohols are correct?

Select one or more of the following:

Volatility is where a substance can easily evaporate at RTP.
Hydrogen bonds decrease the volatility of an alcohol.
Hydrogen bonds increase the volatility of an alcohol.
The solubility of an alcohol decreases when the chain length increases.
Alcohols are non-polar molecules.
Volatility increases as the boiling point increases.

Dehydration is a type of reaction where water is from an organic compound.

The alcohols are heated under reflux with a strong catalyst (H₂SO₄) at 'C.

π-bonds form between adjacent atoms and a molecule is released from the H in the acid and the OH in the alcohols functional group.
