5. IV . Organic Substances
A. Profile
1. Always contain carbon and hydrogen, may also include other elements
2. Covalently bonded chains, rings or small molecules
3. Classified according to # of carbons, bond type and/or functional groups attached

6. a. Prefixes = # of carbons
meth = 1 eth = prop = 3 but = pent = 5
hex = hept = oct = non = dec = 10
b. alkanes : simplest organic compounds – only single bonds
i. Cn H2n+2
ii. –ane ending

7. c. alkene : 1 or more double bond in structure
i. Cn H2n( only works for one double bond)
ii. –ene ending

8. d. alkyne : 1 or more triple bonds in structure
i. Cn H2n-2
ii. –yne ending

9. e. alcohol : hydroxide group attached somewhere
i. follows pattern for alk designation
ii. anol ending – single bonds
iii. enol ending – double bonds
iv. ynol ending – triple bonds

10. What if…….there is a ring ?
Cyclo should preceed the name
