Intro To Organic Chemistry

Question 1

Define empirical formula

Answer 1

Simplest whole number ratio of atoms in a molecule

Question 2

Define molecular formula

Answer 2

Gives the actual number of atoms of different elements in a molecule

Question 3

Define displayed formula

Answer 3

Shows every atom and every bond in a molecule

Question 4

Define structural formula

Answer 4

Shows arrangement of atoms in a molecule without showing every bond

Question 5

Define skeletal formula

Answer 5

Drawn as lines with each vertex being a carbon atom. Carbon atoms not drawn, assumed each c atom has all unspecified bonds as C-H

Question 6

Define structural isomerism

Answer 6

When molecules have the same molecular formula but different structural formula

Question 7

What is positional isomerism

Answer 7

Functional group is attached to the main chain but at a different place

Question 8

What is functional group isomerism

Answer 8

Same atoms but a different functional group due to a different arrangement

Question 9

What is chain isomerism

Answer 9

Hydrocarbon chain organised differently, EG branched chain
