Which stereoisomer ― cis− or trans−1−bromo−3−tert−butylcyclohexa ne ― will react faster in an e2 elimination reaction? select the single best answer.

The cis molecule will react faster.

Explanation:

In the E2 mechanism, we have to have an anti-peri-planar configuration. The hydrogen that is removed and the leaving group should have a configuration of 90º in an anti position (see the figure red hydrogens).

In the trans configuration the ter-butyl group would exercise a steric hindrance upon the hydrogens that can be removed. In the cis configuration we don't have this problem. Therefore the cis molecule would react faster.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
