Chapter 11 - Introduction To Organic Chemistry

Question 1

What is a homologous series?

Answer 1

A homologous series is a group of compounds which have the same general formula. Successive members in a series differ from eachother by a CH2 group

Question 2

What properties do all the members of a homologous series have?

Answer 2

• same general formula
• show a gradation in physical properties
• have similar chemical properties
• have the same functional group
• differ from succesive members by a CH2 group

Question 3

What is the meaning of the term isomerism?

Answer 3

Compounds that have the same molecular formula but different structural forumla are known as structural isomers

Question 4

What are chain isomers?

Answer 4

Chain isomerism occurs when there is more than one way of arranging carbon atoms in the longest chain

Question 5

What are positional isomers?

Answer 5

Positional isomers have the same carbon chain and the same functional group but it is attached at different points along the carbon chain

Question 6

What are functional group isomers?

Answer 6

Functional group isomers are compounds with same molecular formula that have different functional groups

Question 7

What is stereoisomerism?

Answer 7

Stereoisomers are molecules that have the same molecular and structural formula but a different arangement of atoms in 3-D space

Question 8

What is a functional group?

Answer 8

A group of atoms which are responsible for the characteristic reactions of a compound
