How can I convert 3-methylhexane #C_3−C_4# bond from Newman projection to bond line notation?

Answer 1

Start with the most stable staggered Newman projection conformer for 3-methylhxane viewed along the #C_3 - C_4# bond

The most stable conformer for 3-methylhexane viewed along the #C_3 - C_4# bond has two ethyl groups in anti position and gauche interaction between an ethyl group and a methyl group.

Let's determine the groups attached to each atom. If #C_3# is the front atom, you'll see that it has attached the ethyl group in the plane of the page, a methyl group coming out of the plane of the page, and a hydrogen atom going into the plane of the page.

The #C_4# carbon is the back carbon and it has attached the ethyl group in the plane of the page, and two hydrogen atoms out of the plane of the page.

Before attaching the groups to each carbon, you must firts draw the parent chain, hexane

The two ethyl groups are already attached to the #C_3# and #C_4# carbons because thy're part of the parent chain. Since hydrogen atoms are not drawn in bond line notation, the #C_4# carbon will not have anything visible attached to it.

However, the #C_3# carbon will have the methyl group - #CH_3# - attached and visible in the notation.

That is the bond line notation for 3-methylhexane.

Answer 2

To convert the C3-C4 bond of 3-methylhexane from Newman projection to bond line notation, follow these steps:

  1. Identify the carbon atoms C3 and C4 in the Newman projection.
  2. Draw a straight line representing the C3-C4 bond in the bond line notation.
  3. Add the appropriate number of hydrogen atoms to each carbon atom to satisfy their valency.
  4. Incorporate the methyl group attached to C3 and adjust the positioning of atoms as needed to ensure the molecule's structure is correct.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
