Unit A: Organic Chemistry Module 2

Question 1

Hydrocarbon Derivatives

Answer 1

compounds composed of carbon, hydrogen, and one other element

Question 2

Halogenated Hydrocarbon + Physical Property

Answer 2

also known as alkyl halides or organic halides

good solubility in non polar solvents

Question 3

Alcohols

Answer 3

have one or more hydroxyl groups

Question 4

Carboxylic Acids + Physical Properties

Answer 4

carboxyl group is always at the end

higher boiling point then alcohol of same size bc they are more polar causing stronger dipole-dipole forces

Question 5

Esters

Answer 5

contain ester linkage

Question 6

Lowest to Highest Boiling Point

Answer 6

branched hydrocarbons

linear hydrocarbons

halogenated hydrocarbons

esters

alcohols

carboxylic acids

Question 7

Incomplete Combustion Products

Answer 7

CO, CO2, C, H2O, energy

Question 8

Addition Reactions

Answer 8

unsaturated molecule + small molecule = bigger saturated molecule

needs a catalyst

Question 9

Saturation Test

Answer 9

aqueous bromine, if compound is saturated the solution will remain orange if not it will become colourless

Question 10

Substitution Reaction

Answer 10

carbon-hydrogen bond of a saturated compound breaks and is replaced by another atom or group of atoms

uses light as a catalyst

Question 11

Elimination Reaction + Types

Answer 11

creates double bond by eliminating atoms or groups of atoms

Dehydration, dehydrogenation, dehalogenation

Question 12

Dehydration Reaction

Answer 12

removal of water molecule from an alcohol

needs heat as a catalyst

Question 13

Dehydrogenation Reaction

Answer 13

removal of 2 hydrogen atoms

Question 14

Dehalogenation Reaction

Answer 14

halogenated hydrocarbons go through elimination from a base

Question 15

Esterification Reaction

Answer 15

alcohol + a carboxylic acid = water

Question 16

Polmerization

Answer 16

process of linking monomers together

Question 17

Addition Polymers

Answer 17

produced by breaking the double bond of monomers and linking them together

Question 18

Condensation Polymers

Answer 18

two monomers react to form a polymer and another small molecule like water
