L11:Structural Represenation of Organic Compounds

Define Tetrahedral?

3D arrangement of 4 bonds or groups around a central atom, with bond angles of around 109.5 degrees.

What does a Molecular Formula represent and not represent?

Molecular Formula shows the number of each type of atom, but doesn’t show how atoms are connected.

What does a full displayed strcutural formula shows?

Shows all the atoms and covalent bonds

What is the General Formula for a Cycloalkane?

CnH2n

What are 3 types of Structural Isomers?

Chain, Position and Functional group are all Structural Isomers.

What are chain Isomers(structural isomer)?

Are molecules that have the same molecular formula but 1 is linear and 1 is branched. E.g Methylpropane is a branched Molecule.

What are Position Isomers(structural isomers)?

Are molecules that have the same molecular formula but have their functional groups in different places. E.g Butan-1-ol and Butan-2-ol.

What are 2 types of Position Isomers?

Cis and Trans isomers.

What are Functional Group Isomers (structural isomers)?

Are isomers that have had their structures changed so they have different functional groups. E.g Methyl ethanoate or Propanoic acid.
