How many isomeric alcohols are possible for \(\mathrm{C}_{4} \mathrm{H}_{10} \mathrm{O}\). Write the structural formula and IUPAC names for all the isomeric alcohols.

Explain, why alcohols have higher boiling points than alkanes and haloalkanes of comparable mass.

Give the product(s) formed when propan-1-ol reacts with following: (a) Na (b) \(\mathrm{PCl}_{5}\) (c) Conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) (d) \(\mathrm{SOCl}_{2}\) (e) \(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} / \mathrm{H}^{+}\) (f) Conc. HBr

What are the different products obtained by the treatment of ethanol with concentrated \(\mathrm{H}_{2} \mathrm{SO}_{4}\) at \(110^{\circ}, 140^{\circ}\), and \(170^{\circ} \mathrm{C}\) ?

What happens when: (a) Ethanol is treated with iodine in a strong alkaline medium. (b) tert. butanol is passed over the heated copper at \(300^{\circ} \mathrm{C}\). (c) Ethanol is treated with ethanoic acid in presence of conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\)

What is Lucas reagent? How is it used for identification of \(1^{\circ}, 2^{\circ}\), and \(3^{\circ}\) alcohols?

What is the function of anhydrous \(\mathrm{ZnCl}_{2}\) in Lucas reagent?

Giving reasons, arrange the following alcohols in their increasing order of reactivity with \(\mathrm{HBr}\). (i) \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH}\), (ii) \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH}\), (iii) \(\left(\mathrm{CH}_{3}\right)_{2} \mathrm{CHOH}\).

Are alcohols stronger or weaker acids than water? Explain.
