1. Draw the possible E2 products and circle the Zaitsev products.
2. Draw a Newman projection for the preferred anti-periplanar conformation leading to the Zaitsev product.
3. Predict the stereochemistry of the Zaitsev products based on your Newman projection.
Hi! Can someone help me go through the correct steps? Ignore the pen marks I made:)

For the following dehydrohalogenation (E2) reaction, draw the
Zaitsev product(s), showing the stereochemistry clearly. If there
is more than one organic product, both products can be drawn in the
same box.the hint:Consider that the reaction is an elimination in the presence of
a relatively small base to give the Zaitsev product, which is the
most stable. Also consider the stereochemistry of the reactant and
that the elimination must be anti-periplanar.

HV U SIBILHIL Styles Shapel Font Paragraph Drawing Practice Problems Cyclohexanes are not the only occasions for the formation of anti-Zaitsev products in an E2 reaction. Consider (2R,3S)-2-chloro-3-methylpentane. Draw it in a Newman projection looking down the C2-C3 bond, being careful to preserve the stereochemistry. Then use the Newman projection and the requirement for anti-periplanar geometry in the elimination to predict the double bond geometry that is formed.
