The compounds 1-butyne and 2-butyne can be distinguished by using:
Correct answer: C. Tollen's reagent
- A. Bromine water
- B. KMnO4 solution
- C. Tollen's reagent
- D. Chlorine gas
Explanation
1-Butyne is a terminal alkyne with an acidic hydrogen, while 2-butyne is internal. Cold dilute KMnO4 reacts with terminal alkynes to form a diol or oxidizes them differently than internal alkynes. Thus, KMnO4 test distinguishes 1-butyne from 2-butyne.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.

For preparing monoalkyl benzene, acylation process is preferred rather than direct alkylation because:
Unsaturated carbon with how many bonds at the carbon site is known as alkynes?
The main product formed when benzene is alkylated with n-propyl chloride in presence of anhydrous AlCl3 is:
When acetylene and H2S react in the presence of hot Al2O3, the product formed is:
An alkylhalide (RCI) reacts with Li in ether medium to form RLi, which in turn reacts with H2O to 2-methylbutane. The halide (RCl) also reacts with Na in ether to form 2,7 dimethyloctane. The structure of the alkylhalide is:
The ozonolysis of an olefin gives propanone (acetone). The olefin is:
