Halogenoalkanes

Question 1

2 different types of mechanism in hydrolysis of halogenoalkane s

Answer 1

Sn1
Sn2

Question 2

Sn1

Answer 2

Only 1 reactant molecule or ion is present in the rate determining slow step of this reaction

Question 3

What halogenoalkanes undergo Sn1?

Answer 3

Tertiary sometimes secondary

Question 4

How many steps does Sn1 occur in?

Answer 4

2

Question 5

Sn1 rate equation

Answer 5

Only has 1 molecule in it: shows only 1 molecule must be present in the rate determining step

Question 6

Sn1 hydroxide ion reacts…

Answer 6

After the rate determining step because it is not in the rate equation: only 1 molecule present in rate determining step

Question 7

Intermediate phase in

Answer 7

Sn1 where the polar bond breaks between carbon and halogen

Question 8

Why do tertiary halogenoalkane undergo sn1?

Answer 8

Because due to the presence of 3 alkyl groups to the carbon that the halogen is bonded to, there is little space for the OH- nucleophile to attack the carbocation
So must occur in 2 steps
