Organic Chemistry

What’s in a name. And so it is with organic chemistry. The compounds that form with carbon are responsible for life itself. Therefore, understanding the amazing compounds that form from carbon and being able to name some of them is a step towards understanding environmental engineering.

Lecture 7Organic Chemistry

(Chemistry IV)

Common Reaction Types Review

Let’s play…Is it Organic or Inorganic Chemistry

• happens in the environment• forms compounds with carbon• is important to life on earth• occurs in the ground• can go from one to the other• based upon 8 electrons• forms complexes with water

Let’s play….Is it natural or synthetic

• vinegar• teflon• fragrance• advil• botulism toxin• polypropylene• olefin

Writing Molecules…

• Structural• Linear• Condensed• Kinky

Alkanes and Alkenes

• Straight or branched chains of carbon

Meth – 1 Eth – 2 Prop – 3 But – 4 Pent – 5 Hex – 6

alkanes have single bonds between carbons,

alkenes have more…

Hept – 7 Oct – 8 Non – 9 Dec – 10 Undec – 11 Dodec – 12

Common Functional Groups

Ringed Alkanes vs Aromatics

– Aromaticity is the sharing of electrons around a ringed structure

Form follows function….
