Answer 2

Nickel catalyst

423k

Question 3

Alkene to alcohol

Hydration

Answer 3

STEAM (water gas)
Concentrated acid catalyst like H3Po4
-gives two possible products

Question 4

Alkene to haloalkane

Electrophilic addition

Answer 4

1) addition of halogen
2) addition of hydrogen halide (two products)
- room temp may have to bubble

Electrophilic addition

Question 5

Oxidaition of primary alcohol to adlehyde

Colour change?

Answer 5

• K2Cr2O7/ H2So4
  +1[O] to give one h2o
• gentle heat under distill,

Dicrhomate turns orange —>

Question 6

Primary alcohol to carboxylic acid

Answer 6

• K2Cr2O7/ H2So4
• 2[O] to give one h2o
• string heat under reflux with excess dichromate

Orange ti green cr2972- to cr3+

Question 7

Secondary alcohol to ketone

Answer 7

• k2cr2o7/h2so4
• 1[O] to give one h2o
• reflux

Oeange ro green

Question 8

Alcohol to alkene + water

Dehydration

Answer 8

Concentrated acid catalyst like H2So4

- reflux

Question 9

Alcohol to haloalkane

Substitution with sodium halide

Answer 9

Add sodium halide and h2so4

• reflux
• hydrogen halide made in vito and rescts with alcohol to give haloalkane

Gives halolakne water snd NaHCo3

Question 10

Haloalkane to alcohol

Nucleophillic substitution

Answer 10

Add a source of hydroxide ion like NaOH or water

- reflux at 60°

Question 11

DOESNT COUNT but radical substitution of ozone

Answer 11

Cl- + O3—> clo- + o2
Clo- + o —> o2

O3 + o —> 2o2
