(a)

Interpretation Introduction

Interpretation:

The structure of the major product obtained from (R,R) isomer of the amine is to be drawn.

Concept introduction:

In Hoffman’s elimination reaction, the less substituted alkene as the more favourable product, whereas according to Zaitsev rule more substituted alkenes are considered as more favourable product. The notations EorZ are used to describe the geometry around the double bond of an alkene, whereas nomenclature cis or trans is used to describe the relative configurations (RorS). In the cis or trans compound, the molecular formula remains same but arrangement of the atoms in space is different. Cis or trans and EorZ are not interrelated to each other.

(b)

The formation of the Zaitsev product using stereochemical drawings of the transition states are to be shown.

The sum of the numbers in the name of isA. 11; B. 13; C. 10; D. 12; E. none of the other answers iscorrect. I believe the awnser should be E to this problem but the solution to this problem is D 12. I'm honestly unsure how that's the solution. If you can please explain the steps to this type of problem and how to approach a problem like this it would be greatly appreciated!
