haloalkanes

Question 1

nucleophile

Answer 1

electron pair donor

Question 2

nucleophilic substitution of haloalkanes to form alcohols

Answer 2

reagents = aqueous alkali
conditions = heat under reflux
forms an alcohol and a metal halide

Question 3

nucleophilic substitution of alcohols to form haloalkanes

Answer 3

reagents = NaX, H2SO4
conditions = heat under reflux
forms a haloalkane and NaOH

Question 4

reactivity of haloalkanes

Answer 4

reactivity depends on the bond enthalpy of the C-X bond
bond enthalpy decreases going down the group
therefore reactivity increases

Question 5

measuring rate of hydrolysis

Answer 5

reagents = AgNO3
conditions = ethanol solvent and heat
measure time taken for precipitate to appear

Question 6

ozone depletion equation

Answer 6

O3 + O -> 2O2
