Question

1.37 Consider the X-H bond, in which X is an atom other than H. The H in a polar bond is more acidic (more easily to moved) than the H in a nonpolar bond. Considering bond polarity, which hydrogen in acetid, CH,C-OH, do you expect to be most acidic? Write an equation for the reaction between acetic acid and sodium oxide.

Answer 1

For ease of understanding I would like to tell you that what is acidity :-

Any species which can give H+ ion or proton easily is called acidic species. This H+ ion is only hydrogen whose electron is lost.

Let is X-H bond if electron is easily pulled by X toward itself then electron goes on X atom. In this condition hydrogen remains only in the form of H+ . Then we can say that X-H is acidic because it can provide H+.

Now we see acidity in polar & non polar bonds:-

1) Polar bond - Generally in the molecule like X-H , the atom X is more electronegative than H.

Electronegative means tendency to pull electron of bonds towards itself . So X can pull electrons towards itself than hydrogen. When a bond is made up of two elements whose electronegativity is different such type of bond is called polar bond. In this bond electrons can be pulled by more electronegative atom.
