Q26 / 90 · JEE Main 2023 (29 Jan Shift 2) · Chemistry

Total number of acidic oxides among $N_{2} O_{3}, {NO}_{2}, N_{2} O, {Cl}_{2} O_{7}, {SO}_{2}, CO, CaO, {Na}_{2} O$ and $NO$ is _____ .

Correct answer: 4

Solution

Acidic oxides are oxides of non-metals. Thus out of the given compounds, acidic oxides are :

N_{2} O_{3}, {NO}_{2}, {Cl}_{2} O_{7}, {SO}_{2}

Hence, the correct answer is 4.
