Short Answer Type

Dipole moment of phenol is smaller than that of methanol. Why?

Ethers can be prepared by Williamson synthesis in which an alkyl halide is reacted with sodium alkoxide. Di-tert-butyl ether can’t be prepared by this method. Explain.

Why is the $\mathrm{C}—\mathrm{O}—\mathrm{H}$ bond angle in alcohols slightly less than the tetrahedral angle whereas the $\mathrm{C}—\mathrm{O}—\mathrm{C}$ bond angle in ether is slightly greater?

Explain why low molecular mass alcohols are soluble in water.

Explain why $\mathrm{p}-$nitrophenol is more acidic than phenol.

Explain why alcohols and ethers of comparable molecular mass have different boiling points?

The carbon-oxygen bond in phenol is slightly stronger than that in methanol. Why?

Arrange water, ethanol, and phenol in increasing order of acidity and give a reason for your answer.
