Mar 27, 2020 · There are multiple perspectives one can choose when drawing a Newman projection. When drawing a Newman projection, we focus on the conformation of one C-C bond at a time, and ignore all the other conformations. The rotational energy diagram of propane is a sine wave with three maxima, just like ethane. Pretty straightforward, hopefully. Chemistry questions and answers. Translate the given theoretical conformer from the Newman projection to its wedge-and-dash drawing. (Replace the provided placeholder H atoms with the appropriate atom/group). Incorrect. The drawn configurations of both sets of substituents (F, Br, and CH3; H, Cl, and OH) differ from that in the Newman projection.It does not matter if we make the Br a wedge or a dash. It is important to mention the fact that there are two β-hydrogens! The number of β-hydrogens is ultimately what explains the stereochemistry of E2 reactions. To demonstrate this, we will use the Newman and sawhorse projections of the alkyl halide participating in the E2 elimination.
