Example 1 · difficulty 2/5

In IUPAC naming, the parent chain is selected to include the:

A. largest number of substituents only
B. alphabetically first substituent
C. fewest carbon atoms
D. principal functional group and maximum relevant multiple bonds

Example 2 · difficulty 1/5

Numbering of a parent chain gives the principal functional group the:

A. lowest possible locant
B. highest possible locant
C. alphabetical locant
D. same locant as every substituent

Example 3 · difficulty 1/5

B. alphabetically
C. by decreasing locant
D. randomly

Frequently asked questions

Are these official NEET 2025 Chemistry General Organic Chemistry 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 2025 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.
