Text Solution

Verified by Experts

The correct Answer is:
B
Unsymmetrical alkyne gives two products with catalytic dehydration and with HBO reaction, where as with `Sia_2BH + H_2O_2+O^(-) H`, it gives only one product. more bulky `Sia_2BH` attacks on the less hindered triple bond to give only one product.
