1

Reactivity of haloalkane, nucleophilic substitution

C-H, polar H is more electronegative than C
C attracts nucleophiles, slightly positive charge
Nucleophile replaces halogen,

2

Nucleophiles

Donate lone electron pairs

3

Hydrolysis

Nucleophilic substitution
Chemical reaction involving water, aqueous hydroxide, causes non breaking in molecule
Reflux, NaOH, form alcohol

4

Hydrolysis and C-H bond strength

C-H broken, hydroxyl replaces hydrogen
Lower down group, bond enthalpy decreases, strength of bond falls, react at faster rate

5

Hydrolysis investigation

Halide ions produced, test with Ag+ to form silver halide precipitate
Nucleophilic reaction in water, NO3
Reaction carried out in ethanol solvent

6

Hydrolysis of primary, secondary, tertiary haloalkanes

Higher structure, hydrolysed faster
CX bond breaks by heterolytic fission, form 3rd carbocation and halide
Hydroxyl nucleophile attack’s carbonation, form organic product
Increased rate, increased stability
