Answer

1Step 1: Wedge and Dash Representation

Wedge and dash projection is a way of representing a molecule in 3-D in which three types of lines are used to represent the structure in 3-D.

Solid lines are used to represent the bonds that are in the plane of the paper.

Dashed lines are used to represent the bonds that extend away from the viewer (behind the paper)

Wedge shaped lines are used to represent the bonds that are oriented towards the viewer ( coming out of the paper plane)

For example: Wedge and dash representation of methyl alcohol is-

Methyl Alcohol

2Step 2: Newmann projection of most stable conformation of Pentane

We know that the most stable conformation of a molecule is the one wherein the bulky groups of molecule lie as far apart as possible i.e., staggered conformation. So, the Newman projection for most stable staggered conformation of pentane is-

Anti
