Question

Draw the line structure for 2-bromo-3-methylhexane and draw all the Newman projections around C3-C4 carbon, C3 carbon in the front.

Answer 1

Answer 2

To draw the line structure for 2-bromo-3-methylhexane, we first need to determine the placement of the bromine atom and methyl group. Based on the name, we can identify the following:

• The compound is a hexane, which means it has six carbon atoms in a straight chain.

• The bromine atom is attached to the second carbon (C2).

• There is a methyl group attached to the third carbon (C3).

Using this information, we can draw the line structure for 2-bromo-3-methylhexane:

CH3 - C - CH2 - CH2 - CH2 - CH3 | C

Now, let's draw the Newman projections around the C3-C4 carbon bond with the C3 carbon in the front.

1. Newman Projection looking towards C3 carbon:

H3C - C - CH2 - CH2 - CH2 - CH3 | Br

In this Newman projection, we are looking towards the C3 carbon, and we can see the other substituents attached to the neighboring carbon (C4). The H represents the hydrogen atoms.

2. Newman Projection looking away from C3 carbon:

      C

CH3 - C - CH2 - CH2 - CH2 - CH3 | Br

In this Newman projection, we are looking away from the C3 carbon, and we can see the other substituents attached to the neighboring carbon (C4). The H represents the hydrogen atoms.

These Newman projections provide a perspective on the arrangement of substituents around the C3-C4 bond in 2-bromo-3-methylhexane.
