Question

For which mechanism, the first step involved is the same
E1 and SN1 or Sn1 and E2 ​

Answer 1

$\rm\huge\underline{Answer}$

the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.

Answer 2

Answer:

E1 and Sn1

Explanation:

SN1 and E1 are grouped together because they always occur together. ... Both E1 and SN1 start the same, with the dissociation of a leaving group, forming a trigonal planar molecule with a carbocation. This molecule is then either attacked by a nucleophile for SN1 or a base pulls off a b-hydrogen for E1.
