Interpretation: The conversion of given Newman projection into equivalent line-angle formula and the IUPAC name of the given compound are to be stated.
Concept introduction: The rules for the naming of
- Firstly the longest carbon chain is chosen and the naming of chain is done accordingly to the number of carbon atoms that are present in the chain.
- Numbering of the chain is done in such a way that the substituent groups are placed at the lowest position.
- Naming of substituent groups is done by replacing–ane with –yl.
- If different types of substituent groups are present, then they will be written in an alphabetical order.
- If a substituent is present more than one time, then prefixes like di, tri, tetra are used depending on the number of times that particular substituent group appears in the chain.

Translate this drawing to the most stable Newman projection.arrow_forwardHow do I draw the Newman projection for each line structure? This is for organic chemistry.arrow_forwardLabel a curve of potential energy vs. dihedral angle for the Newman conformations of 2,3-dimethylbutane. In each case, the C-2 to C-3 bond rotates in the clockwise direction. Step 1: Translate line-bond notation to the Newman projection. Step 2: Identify Newman projections for each rotation. HI ||| H Step 3: Identify the relative stability of each Newman projection. Step 4: Construct the energy diagram. Step 2: Identify the Newman projections for each rotation (continued). As the back carbon rotates, the Newman projections alternate from staggered to eclipsed and back again. Fill in the remaining conformations for each conformation labeled with the angle of internal rotation from the starting Newman projection.
