Solution
The correct option is B False
Consider the following compounds.
(i) CH3−CH2−CH2−C≡CH pent-1-yne
(ii) CH3−CH(CH3)−C≡CH 3-methylbut-1-yne
(iii) CH3−CH2−C≡C−CH3 pent-2-yne
The compounds (i) and (iii) are position isomers and the compounds (i) and (ii) are chain isomers.
The chain isomers differ in the chain of carbon atoms.
The position isomers differ in the position of triple bond.
