Organic Reaction

Question 1

Combustion

Answer 1

Hydrocarbons (and alcohols) burn in air to produce light/heat energy, CO2, and H2O

Question 2

Complete Combustion

Answer 2

Oxidation

hydrocarbon + O2 = CO2 + H2O

Question 3

Incomplete combustion

Answer 3

hydrocarbon + CO2 = C + CO + CO2 + H2O

Question 4

Substitution

Answer 4

Replacement of hydrogen for a halogen atom or functional group in an alkane

Question 5

What is required for a substitution to occur?

Answer 5

F2 is vigourous, Cl2 and Br2 need UV or heat

Aromatics require a catalyst

Question 6

Halogenation

Answer 6

Replacement of one or more hydrogen atoms in an organic compound by a halogen (C-H bond broken, C-X formed)

Question 7

alkane + halogen 2 + UV/heat

Answer 7

haloalkane (alkyl halide) + hydrogen halide

Question 8

aromatic + halogen 2 + catalyst

Answer 8

haloaromatic + hydrogen halide

Question 9

alcohol + hydrogen halide

Answer 9

haloalkane + water

Question 10

haloalkane + base (NaOH)

Answer 10

alcohol + salt (Na halide)

Question 11

Addition

Answer 11

Reaction of alkenes and alkynes where an atom (H or X) is added without the loss of a hydrogen atom

Double/triple bond is broken

Question 12

Addition of Halogen

Answer 12

Halogenation

alkene + halogen 2 = haloalkane

Question 13

Addition of Hydrogen

Answer 13

Hydrogenation

requires Pt catalyst, heat, and pressure

alkene + H2 = alkane
