-O-H

Question 3

Carboxylic acids functional group

Answer 3

C=O-O-H

Question 5

how is crude oil separated into different hydrocarbon fractions

Answer 5

1 - Oil heated until most of it has turned to gas. Gas enters a fractioning column
2 - When the substances that make up crude oil reach a part of the column where the temp. is lower than their boiling point they condense
3 - longer hydrocarbons = higher boiling points
4 - shorter hydrocarbons = lower boiling points
5 - You end up with crude oil mixture separated out into different fractions. Each fraction contains mixture of hydrocarbons with similar boiling points.

Question 6

conditions for cracking

Answer 6

• 600-700 degrees
• silica/alumina for catalyst

Question 7

Alkane general formula

Answer 7

CnH2n+2

Question 8

are alkenes saturated or unsaturated and why

Answer 8

unsaturated because they can make more bonds (double bond can open up)

Question 9

is crude oil a renewable or non-renewable source?

Answer 9

non-renewable

Question 10

what is a homologous series?

Answer 10

a group of compounds that can all be represented by the same general formula

Question 11

what is a functional group

Answer 11

group of atoms that determine how a compound typically reacts
