Organic Chem

Question 1

Hydrocarbon

Answer 1

a compound containing only carbon and

hydrogen atoms

Question 2

Saturated Compound

Answer 2

a compound in which all of the

bonds between carbon atoms are single bonds

Question 3

Unsaturated Compounds

Answer 3

a compound in which there is at

least one double and/or triple bond between carbon atoms

Question 4

The functional group

Answer 4

an atom or a group of atoms that form the centre of chemical activity in the molecule

Question 5

Homologous Series

Answer 5

a series of similar compounds which have the same functional group and have the same general formula, in which each member differs from the previous one by a single CH2 unit

Question 6

Alkene General Formula

Answer 6

CnH2n

Question 7

Alkane General Formula

Answer 7

CnH2n+2

Question 8

Hydroalkane General Formula

Answer 8

CnH2n+1 X

Question 9

How molecular mass affects IMF

Answer 9

• Both have London IMF
• larger molecular=more electrons per molecule= overall greater electron density
• Greater momentary dipoles
• More energy required
• Higher boiling Point

Question 10

How surface area affects IMF

Answer 10

• Both gave London Forces
• Linear, more surface area, more intermolecular forces
• stronger intermolecular forces

Question 11

Which IMF is stronger in Carboxylic acids and Alcohols

Answer 11

Carboxylate acids have a greater number of Hydrogen bonding, stronger IMF, requiring g more energy, higher boiling point

Question 12

Functional group for Alkanes

Answer 12

/
-C-
/
Saturated hydrocarbon

Question 13

Functional group for Alkenes

Answer 13

. /
C==C
/. \

Double carbon-carbon bond

Question 14

Functional Grouo for HaloAlkenes/ Aykly Halides

Answer 14

Halogen atom bonded to a carbon atom

-X

Question 15

Functional group for Alcohol

Answer 15

Hydroxyl group

-O-H

Question 16

Functional group for Carboxylic Acids

Answer 16

Carboxylic group
O
ll
—C—O—H

Question 17

Functional group for Esters

Answer 17

Estergroup
O
||
—C—O

Question 18

Viscosity

Answer 18

An indication of how easily a liquid can flow. Therefore since a stronger I!F will have a resistance to flow, temperature affects viscosity.

Question 19

What’s with the viscosity of oil?

Answer 19

Oil is non polar, and would therefore have London forces and would flow easily however that isn’t the case because oil has very long carbon chain molecules

Question 20

Haloalkanes gen formula

Answer 20

CnH2n+1X

Question 21

Alcohols gen formula

Answer 21

CnH2nOH

Question 22

Physical prop:
4 Carbons
5 Carbons
12 Carbons

Answer 22

4C= Room temp gas
5C= Liquid
12C= Solid but soft

Question 23

Organic molecules

Answer 23

molecules containing carbon atoms with the exception of carbon dioxide, carbon monoxide, diamond, graphite, carbonates (or bicarbonates), carbides and cyanides

Question 24

Saturated compound

Answer 24

a compound in which all of the bonds between carbon atoms are single bonds

Question 25

Unsaturated compound

Answer 25

a compound in which there is at least one double and/or triple bond between carbon atoms
