Introduction to Organic Chemistry – Dr. Toews 3 lectures on Organic Chemistry (lab next week on buffers) 2 lectures on Chemistry of Life (Dr. Sancar) - transition from general and organic chem to biochemistry - lab 6 on functional groups and organic molecules Review, then Exam 2 Then we start Biochemistry (Dr. Sancar) - amino acids, proteins, & enzymes - lab that week biomolecules and common biochemical Rx   Reminder   that   SI   groups   are   a   great   way   to   understand   difficult   material Peer tutors are great too! (Tue/Wed, 6-9 PM, Dey Hall) Also   optional   review/help   session   every   Tuesday   at   2   PM   (312   Carrington)

Introduction to Organic Chemistry – Dr. Toews Organic molecules  a re   covalent compounds  c o m po s e d o f  carbon (C).    Carbon-carbon bonds  fo rm   “structural skeletons”  o f o rg a nic  m o le c ule s . “Functional groups”  o n b io m o le c ule s  de te rm ine   function Virtually ALL biomolecules are organic molecules   O the r  common elements  (b e s ide s  C ) in  bioorganic compounds  inc lude :   -  hydrogen (H)   -  oxygen (O) - nitrogen (N) - phosphorus (P) - sulfur (S) We need some  basic organic chemistry knowledge  so we can understand   and appreciate all the  biochemistry  that’s coming soon. in approx. order of prevalence in biomolecules

The “Birth” of Organic Chemistry Helps scientists understand that all matter, living and nonliving,  behaves according to the same chemical laws and principles.  Jöns   Jakob   Berzelius (1779-1848) 1807 - coins term  “organic”  for  C-containing compounds   - “vital force” present only in living organisms         is required to form organic compounds.   - can’t make them in the lab Friedrich   Wöhler (1800–1882) 1828 - tries to make ammonium cyanate from potassium cyanate   and ammonium sulfate; accidentally makes  urea  instead.  - first organic molecule synthesized entirely from inorganic material 2 HN C NH 2   ll   O Urea Father of organic chemistry

An amazing range of molecular structures from C itself Graphite Diamond Slippery(good for lock  picking) because of 2-d  composition Very rough, hard to break  because of 3-d shape

Objectives By the end of this lecture, you should:  - understand the structure of the C atom, including its tetrahedral nature  - understand the nature of single, double, and triple C-C bonds  - understand the structures of alkanes, alkenes, and alkynes  - know the difference between molecular, condensed structural, and full      structural formulas of hydrocarbons  - be able to name simple hydrocarbons  - be able to draw simple hydrocarbons given their names or molecular      formulas  - know a little bit about structural isomers Suggested readings:
