what do primary, secondary and tertiary
haloalkanes look like?
1. polar - due to the more electronegative halogen
2. insoluble in water - cannot form hydrogen bonds with H₂O
what are the properties of haloalkanes?
3.higher m.p/b.p of than corresponding alkane as the polar C-X bond forms
permanent dipole-dipole interactions which are stronger than london forces and
need more energy to overcome
-there is in an increase in the number of e⁻ in the halogen
what is the trend in m.p/b.p down group
-higher m.p/b.p down the group of a haloalkane with the same number of
7?
carbons
electron pair donor
what is a nucleophile + examples?
-OH , H₂O , :NH₃
what type of mechanism do haloalkanes nucleophilic substitution as the polar C-X bond creates partial charges
react by and why?
reagents: haloalkane, H₂O, OH⁻ (any source of
OH⁻)
what are the reagents and conditions of
conditions: warm (40°-60°) or heat under reflux
hydrolysis of a haloalkane?
and ethanol solvent (as haloalkanes are
immiscible in H₂O)
why is the nucleophile on the LHS and -LHS due to the repulsion between OH⁻ and C𝛿+
what type of fission occurs? - C-X bond beaks by heterolytic fission
- add haloalkane to ethanol
how do we measure the rate of hydrolysis - add AgNO₃ (aq) to haloalkane and start the timer
of a haloalkane? - stop the timer when a ppt. forms
- calculate rate using 1/time
