interaction (water-hating)
non-polar molecules do not dissolve in water
- amphpathic : a single molecule has two portion, polar and non-polar
fatty acids form micelles
☆ lowering energy makes the system more stable and more likely to exist
2. Hydrogen bond
electrostatic interaction + dipole-dipole interaction
hydrogen bond donor : H
hydrogen bond acceptor : O, F, N
*Background*
Acetyl acetonate (2,4-pentanedionato, acac), CH3COCH2COCH3는 약산으로 수용액에서 이온화 할 수 있는 전형적인 β-didetone이다.
CH3COCH2COCH3 ↔ H+ + CH3COCHCOCH3-
이 때 생성된 음이온은 금속과 착물을 형성하는 리간드(donor-산소)로서 역할을 한다. 일반적으로 결정성 고체로 분리되는 착물은 중성이기 때문에
Reasons of using Cellulose
Why Cellulose?
There are Abundant resources in Earth.
- Don’t have to worry about running out the energy.
We don’t need to waste food.
- Solve the ethic problems for using other biomass.
We can reduce GHG(Green House Gas).
- Eco friendly energy.
What's the problems?
It is difficult to separate the cellulose from wood.
- Components of wood :
Writing Net Ionic Equations
Write the balanced molecular equation.
Write the ionic equation showing the strong electrolytes completely dissociated into cations and anions.
Cancel the spectator ions on both sides of the ionic equation
Check that charges and number of atoms are balanced in the net ionic equation
Write the net ionic equation for the reaction of silver nitrate with sodium ch
1. Monolayer of molecules formed by self-assembly ie., the structures are formed
without external intervention.
2. The structure is organized by utilizing weak interactions such as
H-bonding, van der Waals interactions and there are numerous
interactions of this kind in a structure which make it stable.
3. Nature uses the same process of self-assembly to produce comple
