Question

The chemical reaction :
`(CH_(3))_(3)CBr overset(KOH(alc.))underset(-H_(2)O, -KBr)rarr (CH_(3))_(2)C=CH_(2)` is and example of
A. Nucelophilic substitution
B. Electrophilic substitution
C. Free radical substituion
D. `beta-` Elimination

Answer 1

Correct Answer - `d`
`E1` and `E2` are both called `beta-` elimination because `beta-H` (most acidic) is removed by base. But `E2` is also called anti or trans-elimination.
