What amphipathic molecules?  Molecules that have both a polar and a non polar region In terms of water, what is a hydration shell of interaction?  Water molecules will surround the polar/charged molecules in a cage Why is water good at dissolving charged/polar molecules?  Water is dipolar, so it can hydrogen bond with itself and other molecules Why does water have an unusually high boiling point?  It can hydrogen bond with itself What does solubility in water depend on?  ...

Which of the following statements accurately describes the difference between a sigma (σ) and a pi (π) bond? A. Pi bonds form from the side-to-side overlap of hybridized sp, sp^2, sp^3 superscript orbitals. B. Sigma bonds form from the end-to-end overlap of two hybridized s or p orbitals. C. The maximum number of σ versus π bonds between two atoms are different, but the energy level of the two bonds are the same. D. Only sigma bonds use hybridized orbitals to overlap in forming the b...
