Consider carbon allotropes diamond and graphite. Unlike diamond, graphite conducts electricity. Why? 1. In graphite, there are hybrid orbitals used for bonding that contain electrons. 2. In diamond, all the electrons are in sigma bonds which allow conductivity of electricity. 3. In graphite, there are unhybridized p- orbitals that extend over the entire sheet forming a delocalized pi (1) bonding network where electrons are free to move. 4. In diamond, the bonding electrons have enough energy to move and can therefore conduct electricity. 5. In graphite, the bonds are 109°, which is perfect for electricity conduction.

Malleable. Non- B. Soluble Low conductive conductive Non- High insoluble high conductive conductivity
The picture below shows two atomic orbitals on two neighboring atoms. The orbitals have the specific phases and orientation pictured Use this picture to answer the questions in the table below. If the orbitals come together as shown in the picture, can a molecular orbital (MO) be formed? If you answered yes write the type of orbital formed using the buttons in the palette. If the atomic orbitals can interact to make a molecular orbital, which of the following is the best picture of that MO (in the same orientation)? If the atomic orbitals cannot form an MO, just click Check. yes no 2 D 9 X म. 0 G

Why is the geometric structure of a molecule important, especially for biological molecules?
When two amino acids react with each other, they form a linkage called an amide group, or a peptide link. (If more linkage. are added, a protein or polypeptide is formed.) (a) What are the hybridizations of the C and N atoms in the peptide linkage? (b) Is the structure illustrated the only resonance structure possible for the peptide linkage? If another resonance structure is possible. compare it with the o ne shown. Decide which is the more important structure.
