1.	. Product P, Q ,and R are :
Answer» `P implies I, Q and R implies II` `P and Q` both I and II, `R implies II` P is both I and II, Q and `RimpliesII` P, Q and R `implies ` all II Solution :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.
