haloalkanes key points

Question 1

why do tertiary haloalkanes hydrolyse faster than secondary and primary?

Answer 1

• they are more branched
• have less surface contact
• less london forces, of which are WEAKER
• require less energy to break
  thus faster rate of hydrolysis.

Question 2

conditions for hydrolsis of a haloalkane?

Answer 2

• NaOH (OH-) ion
• reflux
• warm

Question 3

which haloalkane is the most reactive ?

Answer 3

iodo-alkane

Question 4

how can u compare reactivity of haloalkanes?

Answer 4

react hydrolyse haloakane with water to form alcohol.
react alcohol with AgNO3 and halide ions react to form precipitates
record how long it takes for the precipitates to form.
