Chemical Reactions of Haloalkanes
1 . Nucleophilic Substitution Reactions ( SN reactions )
kCN is predominantly ionic and provides cyanide ions in solution , which is ambident nucleophile and bind with carbon side to form as the major product , while AgCN is covalent and form isocyanide as the major product .
Like KCN , KNO2 form R-ONO while AgNO2 produces R-NO2 as product . Vinyl chloride is less reactive towards nucleophilic substitution reactions due to resonance .
