The Solid State — NEET/JEE Questions, Notes & Weightage
Class 12 Physical Chemistry NEET weightage: Medium 154 questions
Covers crystal lattices, unit cells (simple cubic, bcc, fcc), packing efficiency, and defects in solids. Packing-efficiency and density numericals based on unit-cell type are this chapter's most consistent NEET/JEE contribution.

Frequently asked questions
What numerical type is most common?
Calculating packing efficiency or density from a given unit cell type (especially fcc) is the most frequently repeated numerical format.
Are point defects (Schottky, Frenkel) tested?
Yes, as conceptual/definitional questions — distinguishing Schottky defects (ion pairs missing) from Frenkel defects (ion displaced, not missing) is a common question.
