There are 8 diastereomers of1,2,3,4,5,6-hexachlorocyclohexane .
draw each in its more stablechair conformation. one isomer loses
hcl in an e2 reaction nearly1000x more slowly than the others.
which isomer reacts so slowly, and why?

answer can be seen in the attached file

Explanation:

There are 8 diastereomers of1,2,3,4,5,6-hexachlorocyclohexane.

Draw each in its more stablechair conformation. One isomer loses

HCl in an E2 reaction nearly 1000x more slowly than the others.

Which isomer reacts so slowly,and why?

8 diastereomers of 1,2,3,4,5,6-hexachlorocyclohexane in their stable chair conformation.

For E2 Elimination in cyclohexane derivatives the stereoelectronic requirement is that the leaving groups should be both  to each other?-isomer.  although not possible

The -isomer  we are looking for is the only one that does not have any axialchlorines and hydrogen.it  reacts nearly 1000x more slowly than the others

i think a, hope it .
