Terminal alkynes and internal alkynes are the _forms of alkynes.
Correct answer: B. Two
- A. One
- B. Two
- C. Three
- D. Four
Explanation
The correct answer is Option B:Two . Terminal alkynes are alkynes with the triple bond at the end of the carbon chain, while internal alkynes have the triple bond within the carbon chain. Therefore, there are two distinct forms of alkynes, terminal and internal. Option A, C, and D are incorrect because there are only two forms of alkynes, not one, three, or four.
