Physical Properties of Alcohols

Given below are two statements : One is labelled as $\mathrm{Assertion} \mathrm{A}$ and the other is labelled as $\mathrm{Reason} \mathrm{R}$.

$\mathrm{Assertion} \mathrm{A} :$ Butan–$1$–ol has higher boiling point than ethoxyethane.

$\mathrm{Reason} \mathrm{R} :$ Extensive hydrogen bonding leads to stronger association of molecules.

In the light of the above statements, choose the correct answer from the options given below :

In allylic and benzylic alchohols, $-\mathrm{OH}$ group is attached to 

Assertion: Butanol has highest boiling point than ethoxyethane.
Reason: Butanol exhibits intermolecular hydrogen bonding.

Lower alcohols are miscible with water because of the fact that _____

Assertion (A): An ether is more volatile than an alcohol of comparable molecular mass.

Reason (R): Ethers are polar in nature

Which is most VISCOUS ?

Arrange the following compounds in order of their increasing boiling points:

$$\begin{gathered} \left(\mathrm{I}\right) {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{OH} \\ \left(\mathrm{II}\right) {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{OH} \\ \left(\mathrm{III}\right) {\mathrm{CH}}_3\mathrm{CH}\left(\mathrm{OH}\right){\mathrm{CH}}_2{\mathrm{CH}}_3 \\ \left(\mathrm{IV}\right) {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\mathrm{OH} \end{gathered}$$

Alcohol which is most soluble in water is

Which of the following has highest boiling point?

Hydrogen bonding is one of the factor responsible for the solubility of alcohols in water.

The boiling points of alcohols decrease as the alkyl chain branching increases.

Suggest a reason for the large difference between boiling points of butanol and butanal, although they have almost the same solubility in water. Give reason.

The solubility of alcohols in water gradually increases with molecular weight.

Methanol is the most toxic alcohol.
