Coordination Compounds: NEET questions with solutions

NEET tests IUPAC names, denticity and ambidentate ligands, Werner-type ionisation counts, VBT hybridisation and magnetism, crystal-field splitting with high- and low-spin filling, isomerism (geometrical, optical and the structural types) and metal carbonyls. Marks are lost on the -ate ending, on strong- versus weak-field filling, and on spotting a plane of symmetry in trans isomers.
