NEET Chemistry IUPAC Nomenclature MCQ Question
Which of the following statements regarding IUPAC nomenclature of hydrocarbons is correct?
Straight chain hydrocarbons are named with a suffix '-ane' indicating the presence of only single bonds.
Unsaturated hydrocarbons contain only carbon-carbon single bonds and are named with the suffix '-ene'.
All hydrocarbons must contain at least one carbon-carbon double bond to be classified as alkenes.
The prefix in the name of hydrocarbons indicates the presence of functional groups in the compound.
Correct Answer
Detailed Explanation
Statement A is correct as it accurately describes that straight chain hydrocarbons with only single bonds are suffixed with '-ane'. Statement B is incorrect because unsaturated hydrocarbons contain double or triple bonds. Statement C is misleading as alkenes specifically have at least one double bond, not all hydrocarbons. Statement D is false since the prefix indicates the number of carbon atoms, not functional groups.
