4.1.1 Basic concepts of organic chemistry (isomerism, reaction mechanisms, free radical substitution)

Question 1

When will a compound have structural isomers?

Answer 1

When an alkane has 4 or more carbons

Question 2

What is a structural isomer?

Answer 2

Molecules with the same molecular formula but different structural formulas

Question 3

For naming compounds, if the branch has 1 carbon (CH3) what is it called?

Answer 3

methyl

Question 4

For naming compounds, if the branch has 2 carbons (C2H5) what is it called?

Answer 4

ethyl

Question 5

For naming compounds, if the branch has 3 carbons (C3H7) what is it called?

Answer 5

propyl

Question 6

For naming compounds, if there are 2 groups of the same type in a compound, what is the prefix used?

Answer 6

di-

Question 7

For naming compounds, if there are 3 groups of the same type in a compound, what is the prefix used?

Answer 7

tri-

Question 8

What do alkanes react with halogens to form?

Answer 8

haloalkanes and hydrogen halides

Question 9

Why is free radical substitution not the best way to make a haloalkane?

Answer 9

Because multiple products can be formed

Question 10

What is a radical?

Answer 10

A species with an unpaired electron

Question 11

What are the conditions for free radical substitution?

Answer 11

UV light
