Acarbon
Bphosphorus
Cchlorine
Dbarium
Correct Answer

Solution

The element that does NOT form acidic oxide is $$\displaystyle Barium$$.
$$\displaystyle Barium$$ is an alkaline earth metal. It forms basic oxide $$\displaystyle BaO$$.

$$\displaystyle Carbon $$ forms $$\displaystyle CO_2 $$ which is acidic oxide.

$$\displaystyle Phosphorus$$ forms $$\displaystyle P_2O_3$$ and $$\displaystyle P_2O_5$$ which are acidic oxides.

$$\displaystyle Chlorine$$ forms $$\displaystyle Cl_2O_7$$ and other oxides which are acidic oxides.
