Explanation:
Answer:
<u>cis-</u>isomer reacts faster
Explanation:
The missing diagrams in the question are attached in the first image below and the isomers that react faster are shown in the second image attached.
The <u>cis-</u>isomer quickly follows E2 reaction due to the fact that it is locked in a chair conformation whereby chlorine dominates an <u>axial </u>position, as displayed in drawing <u>C </u>as well as the leaving group <u>Cl</u> which is antiperiplanar to a beta proton.
Due to the bulkiness of tert-butyl, the<u> trans-</u>isomer is Basically trapped in a chair configuration, with chlorine occupying an <u>equatorial</u> position as displayed in drawing <u>A</u> below, thus leaving the group isn't antiperiplanar to a beta proton.
Tert butyl favors an equatorial position due to its bulkiness. This makes the Cl to assume an axial position in an isomer
The difference:
From the second image attached below, in the first diagram(1):
Suppose H is antiperiplanar, C-H bond electrons reach antibonding orbitals of C-Cl, assisting in the breakdown of the C-Cl bond and therefore speeding up the process.
From the second diagram(2) in the second image:
Unless Cl is in the axial position would it have β-hydrogen in the antiperiplanar position. Because tert-butyl prefers equatorial location, the Cl occupies equatorial position in the trans isomer.
As a result, the reaction is slower and there is no β-hydrogen antiperiplanar to Cl.
