Question

Assertion In the E2 elimination, β - H and leaving group should be antiperiplanar. Reason In the E2 elimination, base always abstracts unhindered β- H. (A) If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion: (B) If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion: (C) If Assertion: is true but Reason: is false (D) If both Assertion: and Reason: are false

In E2 elimination, β - H and leaving group are in the same plane but anti-conformation. Base can abstract hindered β-H. Thus, Reason is false.

Q. Assertion In the $E 2$ elimination, $β$ - $H$ and leaving group should be antiperiplanar.
Reason In the $E 2$ elimination, base always abstracts unhindered $β - H$ .

If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:

If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:

If Assertion: is true but Reason: is false

If both Assertion: and Reason: are false

In $E 2$ elimination, $β$ - $H$ and leaving group are in the same plane but anti-conformation. Base can abstract hindered $β$ -H. Thus, Reason is false.
