Original practice preview

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

Example 1 · difficulty 3/5

Why is the carbon–chlorine bond in chlorobenzene shorter and stronger than the carbon–chlorine bond in a typical chloroalkane?

A. Chlorine loses all lone pairs in chlorobenzene
B. The benzene ring converts chlorine into a positive ion
C. Resonance gives the bond partial double-bond character, and the ring carbon is sp2-hybridised
D. The bond becomes a pure ionic bond in chlorobenzene

Example 2 · difficulty 1/5

Which rate expression correctly represents an SN2 reaction between bromoethane and hydroxide ion?

A. Rate = k[bromoethane]
B. Rate = k[OH⁻]
C. Rate = k[bromoethane]²
D. Rate = k[bromoethane][OH⁻]

Example 3 · difficulty 2/5

What is the correct decreasing order of SN2 reactivity for the following alkyl bromides?

A. CH3Br > CH3CH2Br > (CH3)2CHBr > (CH3)3CBr
B. (CH3)3CBr > (CH3)2CHBr > CH3CH2Br > CH3Br
C. CH3CH2Br > CH3Br > (CH3)3CBr > (CH3)2CHBr
D. (CH3)2CHBr > CH3CH2Br > CH3Br > (CH3)3CBr

Frequently asked questions

Are these official NEET 2026 Chemistry Haloalkanes and Haloarenes 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 2026 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.
