WebThe hydrolysis of haloalkane, the halogen atom is replaced by an OH group. • the nucleophile approches the carbon atom attached to the halogen on the opposite side to the halogen (minimises repulsion). • a lone pair of electrons on the hydroxide ion is attracted to the +ve carbon. • a new bond is formed between the oxygen and carbon. Weband C-H bonds. These haloalkanes (RX), alcohols (ROH), ethers (ROR), and amines (RNH2, R2NH, R3N) have different properties than alkanes and cycloalkanes because the X, O, and N atoms have valence shell unshared electron pairs and their bonds to C are polar.
