Organic Chemistry

Compounds of Carbon C almost always forms covalent bonds C-C bonds very strong C compounds not very reactive C can make up to 4 single bonds so there are lots of possibilities

Allotropes Different bonding arrangements of the same elements Properties of the compound are different because of the different arrangement

C allotropes C -- 4 allotropes Diamond Graphite Fullerenes Nanotubes

Organic Compounds Covalently bonded compounds containing C Over 12 million exist and new ones are being made or found everyday Main ingredient is C. H, O, N, S, P and halogens can bond to the C atoms Examples Oil -Pharmaceutical Drugs Plastics -Caffeine Proteins -Hair Lipids -Citric Acid Fabrics

Hydrocarbons Simplest organic compounds Made of only H and C 3 types Alkanes- made with only single bonds General formula CnH2n+2 Alkenes- contain double bonds General formula with only 1 double CnH2n Alkynes- contain triple bonds General formula with only 1 triple CnH2n-2 In all hydrocarbons C must make 4 bonds

Naming Alkanes Based on the number of C in the molecule
