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.
