Which of the following statements are true? (i) 1-Propanethiol has a higher boiling point than 1-propanol.
(ii) 1-Propanethiol has a boiling point comparable to CH₃CH₂SCH₃ (ethyl methyl sulfide) .
(iii) 1-Propanethiol is much more acidic than 1-propanol.

(ii) is true because 1-propanethiol and ethyl methyl sulfide, both being sulfide compounds, have comparable boiling points due to similar molecular weights and types of intermolecular forces (van der Waals forces). (iii) is true because thiols (like 1-propanethiol) are more acidic than alcohols (like 1-propanol) due to the sulfur atom in thiols being larger and more polarizable than the oxygen atom in alcohols, making it easier for thiols to donate a hydrogen ion.
