WebAug 19, 2024 · In order to better visualize these different conformations, it is convenient to use a drawing convention called the Newman projection. In a Newman projection, we look lengthwise down a specific bond of interest – in this case, the carbon-carbon bond in ethane. We depict the ‘front’ atom as a dot, and the ‘back’ atom as a larger circle. WebFor example, the Newman projection for ethane looks like the following. The Newman projection is used to check what substituents exist around the C-C bond (bond between carbons), which is the center of the molecule. At the center of the Newman projection, two carbon atoms overlap. The Newman projection is what you see from the side of the axis. hlh parameterWebIn order to convert a Newman projection to the corresponding bond-line structure, you need to look at it from the side.
