Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

Which description matches the Lewis structure of CO₂ that gives all three atoms complete octets and zero formal charges?

A. O=C=O, with two lone pairs on each oxygen
B. O-C-O, with only single bonds
C. O≡C-O, with no charge separation
D. A structure containing one C-O bond and one O-O bond

Example 2 · difficulty 3/5

In the ozone canonical form O=O-O, what is the formal charge on the central oxygen atom?

A. 0
B. +1
C. −1
D. +2

Example 3 · difficulty 4/5

The nitrate ion has three equivalent N-O bonds because of resonance. What is the average N-O bond order?

A. 1
B. 3/2
C. 4/3
D. 2

Frequently asked questions

Are these official NEET 2020 Chemistry Chemical Bonding PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2020 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
