03. Polyhalogen Compounds
HALOALKANES AND HALOARENES

91110 Chloropicrin is obtained by the reaction of

1 steam on carbon tetrachloride
2 nitric acid on chlorobenzene
3 chlorine on picric acid
4 nitric acid on chloroform
HALOALKANES AND HALOARENES

91112 Aryl halides doesn't undergo nucleophilic substitution reactions under ordinary conditions because of
1.approach of nucleophile is retarded
2.carbon carrying halogen atoms is $\mathbf{s p}^{3}$ hybridised
3.the substrate molecule is destabilized due to resonance
4.Partial double bond character between carbon and halogen
