Organic Chem Class #7

OB: Branched Hydrocarbons

Drawing them, naming them, and ISOMERS TOO.

slide2

We’ll need lots of paper, and your thinking caps on.

We’ve learned that ISOTOPES are chemically identical atoms with different atomic masses (different numbers of neutrons) which are the reason for average atomic masses being decimals.

We’ve learned about ALLOTROPES, such as graphite and diamonds, both pure carbon, but bonded differently and with different properties. If you don’t believe that, try to take the regents with a diamond, or get engaged with a pencil!

ISOMERSare organic compounds with the same chemical formula, but different structures, so they have the same molar mass, but totally different properties.

Examples are ethanol and dimethyl ether (what are the structural formulas and the chemical formulas please (do this NOW)

slide3

ethanol + dimethyl ether

CH3CH2OH and CH3OCH3

C2H5OH or

C2H6O and C2H6O

slide4

Branched hydrocarbons will also be isomers. Count the carbon atoms, if all the bonds are single bonds, then equal numbers of carbons will be isomers even though the molecules are “different”.

Try hexane and let’s draw 2,3-dimethyl butane.

slide5

CH3

2,3 dimethyl butane

  • CH3

There’s a methyl group hanging off of the #2 and the #3 carbon. Isomer to hexane.

slide8

Draw 3-ethyl hexane and

3methyl-4,5-dibromo hexane

slide11

n-heptane (or normal heptane) 2-methylhexane 3-methylhexane 2,2-dimethylpentane 2,3-dimethylpentane2,4-dimethylpentane 3,3-dimethylpentane 3-ethylpentane 2,2,3-trimethylbutane
