The structure for the given molecule is to be drawn.

When writing the IPUAC name, the R or S designation is written in parenthesis for each asymmetric carbon atom, and hyphens are used to separate those designations from the rest of the IUPAC name.
(b)
Interpretation:
The structure for the given molecule is to be drawn.
Concept introduction:
When assigning priorities to substituents, the atom having the greater atomic number has the higher priority. In case of comparison between isotopes, the one having the greater atomic mass gets the higher priority. When the fourth priority substituent is pointing away (it is attached by a dash bond) and the first, second, and third priority substituents are arranged clockwise, the configuration is R. When the fourth priority substituent is pointing away (it is attached by a dash bond) and the first, second, and third priority substituents are arranged counterclockwise, the configuration is S. If the fourth priority substituent is attached by a wedge bond, then the clockwise or counterclockwise arrangement of the first, second, and third priority substituents is determined, and that arrangement is reversed before assigning R or S. If the fourth priority substituent is in the plane of the page, then it is switched with the substituent that points away. Then the clockwise or counterclockwise arrangement of the first, second, and third priority substituents is determined, and that arrangement is reversed before assigning R or S.

- Problem: Perform a conformational analysis 2-iodo-2-methylbutane, looking down the C2—C3 bond. Pay attention to the relative energies of the various conformations, but do not concern yourself with the actual energy values. Pleae draw newman projections.arrow_forwardfirst box: Draw the missing curved arrow notation. Add lone pairs of electrons and nonzero formal charges. Second Box: Draw the product that will be produced. Be sure to draw in any hydrogen at chiral centers.
