NEET Chemistry (general) MCQ Question
Which of the following statements about hydrocarbons is correct?
Geometrical isomerism occurs only in alkenes with different groups attached to the double-bonded carbons.
All hydrocarbons can exhibit chain isomerism regardless of their molecular formula.
Benzene can form more than one monosubstituted derivative due to its high degree of unsaturation.
Alkenes can only have one structural isomer corresponding to a given molecular formula.
Correct Answer
Detailed Explanation
Geometrical isomerism is specifically noted in alkenes where the double bond can have different groups attached to each carbon, as indicated in the NCERT context. In contrast, benzene's unique stability results in only one monosubstituted derivative, and not all hydrocarbons exhibit chain isomerism.
