Haloalkane

Question 1

Reactivity of haloalkane, nucleophilic substitution

Answer 1

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

Question 2

Nucleophiles

Answer 2

Donate lone electron pairs

Question 3

Hydrolysis

Answer 3

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

Question 4

Hydrolysis and C-H bond strength

Answer 4

C-H broken, hydroxyl replaces hydrogen

Lower down group, bond enthalpy decreases, strength of bond falls, react at faster rate

Question 5

Hydrolysis investigation

Answer 5

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

Question 6

Hydrolysis of primary, secondary, tertiary haloalkanes

Answer 6

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
