Question

Why does sugar solution became alcoholic on adding yeast?

Answer 1

Because (in simple terms) yeast is a living organism that eats sugar. It consumes the sugar and “poops out” heat, carbon dioxide, and alcohol as the byproducts of its consumption.

This is the basics of fermentation. The same is true of grapes being fermented to create wine, grains being fermented to create beer, maguey being fermented to make pulque, apo, sekmai and kallu in India, and so on.

What you’re tasting is actual alcohol. The yeast is digesting the sugars in the solution and releasing alcohol as the byproduct/waste product. Hence the alcoholic taste.
