Introduction To Organic Chemistry

Question 1

What are the three structures in which a molecule can be represented?

Answer 1

1. Lewis
2. Condensed
3. Skeletal

Question 2

What are alkyl radicals?

Answer 2

Side chains of molecules

Question 3

What are the three types of structural isomerism?

Answer 3

1. Chain
2. Positional
3. Functional grouo

Question 4

What is chain isomerism?

Answer 4

Isomers differ in their carbon skeleton

Question 5

What is positional isomerism?

Answer 5

Differs in the position of the functional group

Question 6

What is functional group isomerism?

Answer 6

Differs in the type of functional group

Question 7

Stereoisomerism?

Answer 7

Compound with the same number and type of atoms bonded to each ither arranged differently in space

Question 8

Types of stereoisomerism?

Answer 8

1. Geometrical (Cis-trans)
2. Optical

Question 9

Why does geometrical isomerism occur?

Answer 9

Due to lack of rotation round a C=C double bond as a result of the presence of a pi bond

Question 10

Optical isomerism?

Answer 10

When a carbon atom has four different groups attached to it so form mirror images of each other but are no superimposable

Question 11

Enantiomers?

Answer 11

Optical isomers that form mirror images but are not superimposable

Question 12

What type of carbon is the chiral centre?

Answer 12

Asymmetric
