NEET 2023 Phase 2 · ChemistryOxide naturePrevious Year Question

The correct sequence given below, containing a neutral, an acidic, a basic and an amphoteric oxide respectively, is:

Answer: (B) $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$ . \textbf{Answer:} (B) $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$ \textbf{Solution:} Classifying each oxide: neutral $=$ $NO$ ; acidic $=$ $CO X_{2}$ ; basic $=$ $CaO$ ; amphoteric $=$ $ZnO$ .

A. $NO$ , $CO X_{2}$ , $ZnO$ , $CaO$
B. $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$ ✓
C. $NO$ , $ZnO$ , $CO X_{2}$ , $CaO$
D. $ZnO$ , $NO$ , $CaO$ , $CO X_{2}$

Correct Answer

(B) $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$

Solution & Explanation

\textbf{Answer:} (B) $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$ \textbf{Solution:} Classifying each oxide: neutral $=$ $NO$ ; acidic $=$ $CO X_{2}$ ; basic $=$ $CaO$ ; amphoteric $=$ $ZnO$ . The required order neutral, acidic, basic, amphoteric is therefore $NO$ , $CO X_{2}$ , $CaO$ , $ZnO$ , which is option B.
