Question

Choose odd one out from CuO,ZnO,PbO,Al2O3

Answer 1

Answer:

Name of the compounds :-

CuO = copper monoxide

znO = zinc monoxide

pbO = lead monoxide

Al2O3 = Aluminium trioxide

here, odd one is Al2O3 (Aluminium trioxide)

because the another compounds are monoxide . according to the question the monoxide are CuO , ZnO, pbO .

but Al2O3 is a trioxide .

there are three oxides in this question and one trioxide is present .

then odd one is Al2O3 .

metals react with oxygen and give certain oxide like monoxide , dioxide , trioxide .

This is your answer....

thanks....
