Summary 5.1

Organic molecule:

• Definition : carbon-based molecule





• It's made out from bond between carbon atoms.
  
  
  
  
  

Inorganic molecule:

• Definition : just opposite of organic molecule(non carbon-based molecule)
  




• Examples: Water(H2O),Oxygen(O2),Ammonia(NH3)

Hydrocarbons:

• Definition:It's the bond between only carbon and hydrogens.




• It's worldwidely used important fuel,such as Methane the fuel used to heat up home.Hydrogen and Nitrogen are frequently found in organic molecules.




• Examples:Methane(CH4)

Functional group:

• Definition: It's a group of atoms within a molecule that interacts in predictable ways with other molecule.




• Some of the functional groups are important in the chemistry of life




• The carbon skeleton and the attached functional group determine the properties of an organic molecule

Hydrophilic:

• Definitions:It means attract water molecules




• Most organic molecules that contain hydroxyl groups are hydrophilic.

Monomers:

• Definition:Small molecular unit that is the building block of a larger molecule

Polymers:

• Definition:Long chain of small molecular units




• It's a straight chain of monomers,much as a train is a string of many individual cars.




• Every living cell has thousands of different kind of polymers.




• When monomer is added to a chain, a water molecule is released.

1.

2.Connection between polymers and monomers is that polymers connect monomers in straight line.
3.A water molecule, dehydration reaction.
