NEET Chemistry (general) MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following statements about hydrocarbons is correct?

A

Alkynes can undergo addition reactions due to their triple bonds.

B

Hydrocarbons are exclusively nonpolar substances.

C

All alkanes have at least one structural isomer.

D

C5H12 has only two structural isomers.

Correct Answer

Option A

Detailed Explanation

Alkynes contain a triple bond, allowing them to participate in addition reactions with dihydrogen, halogens, and hydrogen halides, as noted in the NCERT context. Option B is incorrect because hydrocarbons can have polar and nonpolar characteristics depending on their structure. Option C is misleading as not all alkanes have structural isomers, and option D is incorrect as C5H12 actually has three structural isomers.
