Topic 11- Introduction To Organic Chemistry

Question 1

What is the molecular formulae?

Answer 1

The actual number of atoms in a molecule or element

Question 2

What is the empirical formulae?

Answer 2

Simplest whole number ration of atoms in a compound

Question 3

What is the structural formulae.

Answer 3

The arrangement of atoms in a molecular without showing all the bonds

Question 4

What is the Skeletal formulae

Answer 4

Bonds of carbon skeleton only.

Question 5

What is the displayed formulae

Answer 5

Shows the arrangement of atoms, shows all bonds and atoms in a molecule.

Question 6

What is the structural isomers- chain isomers?

Answer 6

Same molecular formulae arranged differently of carbon skeleton.

Question 7

What is a positional isomerism?

Answer 7

Same molecular formulae, arranged differently position of functional group on carbon skeleton.

Question 8

What is the functional group isomer

Answer 8

Same molecular formulae different functional group.

Question 9

What are structural isomers

Answer 9

Same structural formulae, different atom arrangement in space.
C=C bonded flat therefore planar.
-Atoms cannot rotate around C=C bond and is rigid.
