Q55 / 200 · NEET 2023 (Manipur) · Chemistry

The correct sequence given below containing neutral, acidic, basic and amphoteric oxide each, respectively, is

  • A
    $\mathrm{NO}, \mathrm{CO}_2, \mathrm{ZnO}, \mathrm{CaO}$
  • Correct answer
    B
    $\mathrm{NO}, \mathrm{CO}_2, \mathrm{CaO}, \mathrm{ZnO}$
  • C
    $\mathrm{NO}, \mathrm{ZnO}, \mathrm{CO}_2, \mathrm{CaO}$
  • D
    $\mathrm{ZnO}, \mathrm{NO}, \mathrm{CaO}, \mathrm{CO}_2$

Solution

Oxides Chemical Nature $\begin{array}{cc}\mathrm{NO} & \text { Neutral } \\ \mathrm{CO}_2 & \text { Acidic } \\ \mathrm{CaO} & \text { Basic } \\ \mathrm{ZnO} & \text { Amphoteric }\end{array}$

Hence, the correct answer is option: 'B'.
