ANSWER:
Solution 34SP:
Here, we are going write the synthetic transformations having intermediates.
- 2,2-dibromobutane to but-1-yne
The synthetic transformation with intermediate is given below:
(b) 2,2-dibromobutane to but-2-yne
The synthetic transformation with intermediate is given below:
(c) but-1-yne to oct-3-yne
