Polarity depends on shape:
Unequal = polar
Equal = non-polar
Functional groups:
Cis bonds = bent, fatty acids liquid at room temp, unsaturated, healthy
Trans bonds = fatty acids solid at room temp, saturated, unhealthy
,Bond strengths: covalent > ionic > t > van der Waals
More hydrogen bonds = more solid the substance and higher melting points
- Stronger bonds when 3 atoms are in a line
Hydrophobic effect: the tendency of non-polar substances to cluster in aqueous solutions
,Entropy - disorder in a system
Enthalpy - head contained within molecules
Lesson 3
Life only tolerable within blood pH (7.2-7.6)

**Lower pKa = stronger the acid**
