+# Organic Chemistry
+
+Large number of compounds due to:
+- 4 valence pairs
+- single / double / triple bonds
+- cyclic (ring) structures
+
+## Properties of hydrocarbons
+
+- *Saturated* - all C-C bonds are single
+- Insoluble in water
+- Almost non-polar (similar electronegativities)
+- Only dispersion forces (valence e-)
+- Dispersion forces increase with length
+- Branched molecules have lower density
+
+## Linear (aliphatic)
+
+Alkanes: \ce{C_{$n$} H_{$2n+2$}}
+Alkenes: \ce{C_{$n$} H_{$2n$}}
+Alkynes: \ce{C_{$n$} H_{$2n-2$}}
+
+## Naming hydrocarbons
+
+- Branches end with _-yl_
+- Indicate number of branches with di-, tri- etc.
+- Longest unbranched carbon chain includes function group
