JEE MainChemistryGeneral Organic Chemistry
Given below are two statements : Statement (I) : Cyclohexane and Hex-2-yne are ring-chain isomers. Statement (II) : N-methylpropan-1-amine and N-ethylethanamine are metamers. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- AStatement (I) is false but Statement (II) is true.
- BBoth Statement (I) and Statement (II) are true.
- CBoth Statement (I) and Statement (II) are false.
- DStatement (I) is true but Statement (II) is false.
Correct answer
A. Statement (I) is false but Statement (II) is true.
Step-by-step solution
Statement (I) is false. For two compounds to be isomers, they must have the exact same molecular formula. Cyclohexane has the molecular formula C ₆ H ₁₂ (Degree of Unsaturation = 1), whereas hex-2-yne has the molecular formula C ₆ H ₁₀ (Degree of Unsaturation = 2). Since their molecular formulas differ, they cannot be isomers of any kind. Statement (II) is true. Both N-methylpropan-1-amine and N-ethylethanamine have the same molecular formula ( C ₄ H ₁₁ N ) and both possess the secondary ( 2^ ) amine functional gro
