Given the following organic compounds i. Bromocthane ii. But-2-yne iii. But-1-yne iv. Hydroxybenzene Which one would you not expect to give any form of substitution reaction?
A. i B. ii C. iii D. iv
Correct Answer: B
Explanation
\(\Rightarrow\) Bromoethane and hydroxybenzene would under- go substitution reactions \(\Rightarrow\) Even though both but-1-yne and but-2-yne are very similar, but-1-yne will undergo substitution reaction while but-2-yne will not. This is because but-1-yne is a terminal alkyne while but-2-yne is not
