Chemical Bonding and Molecular Structure: NEET questions with solutions
Tests how precisely a student applies VSEPR theory, hybridisation, and molecular orbital theory to predict molecular shape, bond order, and polarity. Most NEET marks are lost confusing electron-domain geometry with molecular shape, forgetting lone-pair placement rules, or assuming polar bonds always give a polar molecule.
