Answer #1

No, a carbon carbon double bond can not be designated as D or L.

It is because the d and l descriptors are used to designate the direction of specific rotation of chiral compounds, is a convention used to distinguish between enantiomers of chiral monosaccharides and chiral alpha-amino acids, based on the molecule drawn as a Fischer projection in a specific orientation.

Monosaccharides and amino acids are compounds having carbon atoms connected through single bonds.

When a conductor e.g. metal or carbon is immersed in a electrolyte, electric double layer will be formed at the interface of the solid electrode and electrolyte. The equilibrium potential is related to the double-layer formed at the interface. Under the certain circumstance, the double-layer on the interface can disappear, the potential at which no double-layer is called “point of zero charge”. Please explain how it happens. (hint: the double layer is formed due to the difference of free energy...

L-galactose can be prepared from D-galactose by a route that begins with oxidation to D-galactaric acid, which cyclizes to form two six-membered-ring lactones. After separating the lactones and reducing them with sodium amalgam, one lactone returns D-galactose while the other one yields L-galactose. Draw the structure of the lactone that yields L-galactose. - Use the wedge/hash bond tools to indicate stereochemistry. - You do not have to explicitly draw H atoms. - If a group is achiral, do not use...
