HEY MATE!!! ❤❤❤❤HERE'S UR ANSWER!!!❤❤❤
Actually, Hydrogen and Oxygen are highly reactive elements which react almost with all types of metals and nonmetals. So, the nature and similarities in oxides or hydrides could be the basis of classification on behalf of which the elements could be grouped together, because the elements with similar nature will definitely have similar types of hydrides and oxides.
Thus, Mendeleev used the oxides and hydrides for the basis of classification.

Answer:
Mendeleev took the formulae of oxides and hydrides formed by the elements as the basic property for classification because oxygen and hydrogen are very reactive and form compounds with most of the elements. The properties of oxides and hydroxides of elements formed the basis to classify elements into same group or different group. Also the elements in the same group will have oxides and hydroxides with same general formula, thus it is exactly the function of valence electrons in modern periodic table.
