Q15. - Organic Chemistry

Question

Which of the following is (are) possible Newman projections for 2-methylpentane?

Step-by-Step Solution

Answer

The possible Newman projections for 2-methylpentane are A and B.

Step 1. Newman projection

Newman's projection involves the representation of alkane with the help of dots and circles. Two carbon atoms are required in this projection.

Step 2. Explanation for possible Newman projections

The given compound is 2-methylpentane. The possible Newman projections for 2-methylpentane are mentioned below:

                  Staggered conformation

Step 3. Explanation for wrong projection

The compound C is the conformation of 3-methylpentane as shown below:

                             Compound C

Thus, the possible Newman projections for 2-methylpentane are A and B.
