I < II < IV < III
IV < III < II < I
I < II < III < IV
IV < I < II< III
Correct answer is D
| Ethanol | 78°C |
| Propanol | 97°C |
| Butanol | 118°C |
| Pentane | 36.1°C |
Hence, the arrangement is IV, I, II, III.

Which of the following compounds would not give a precipitate with ammoniacal AgNO3 solution?
CH3 C≡CCH3
HC≡CH
CH3C≡CH
CH3CH2C≡CH
Correct answer is A
Only terminal alkyne(simply, the alkyne in which the triple bonded carbon atoms are at the extreme positions.) reacts with ammonical AgNO3 and gives a white precipitate,
therefore, the correct option is A (Non-Terminal Alkyne has a triple bond at any place other than the end positions).
