Introduction to Organic Chemistry

Question 1

Hydrocarbon

Answer 1

Compound containing only carbon and hydrogen

Question 2

Homologous Series

Answer 2

Series of compounds containing the same functional group and display similar chemical properties

Question 3

Functional Group

Answer 3

Atom or group of atoms responsible for a compound’s chemical properties. Same functional group compounds will undergo similar reactions regardless of the size of the molecule it is part of

Question 4

Emperical forumla

Answer 4

Simplest whole number ratio of atoms present in a compound

Question 5

Isomer

Answer 5

Molecules with same structural formula but different arrangement of atoms

Question 6

Structural isomer

Answer 6

Same molecular formula but different structural formula

Question 7

Chain isomer

Answer 7

Different arrangements of carbon skeleton

Question 8

Positional isomer

Answer 8

Same arrangement of carbon skeleton, functional group is attached to a different carbon

Question 9

Functional group isomer

Answer 9

Same atoms arranged different to give a different functional group- different physical and chemical properties

Question 10

Stereoisomer

Answer 10

Same structural formula but different arrangement of atoms in space

Question 11

E-Z isomerism

Answer 11

Form of stereoisomerism that occurs due to restricted rotation around C=C double bond

Question 12

CIP Priority rules

Answer 12

On each carbon on the double bond, group with the highest atomic number is given priority, lowest atomic number given lowest priority
