A student had prepared two cyclo alkenes, a$)1-$ethyl$-2-$methylorciohex$-1-$ene and b$)1$ethylcyclohex$-1-$ene. The student then further performed oxidative cleavage on the cyclohexenes. After the student ran their two reactions labelled Oxidative Cleavage $1$ and Oxidative Cleavage $2,$ they realized they forgot to write down which cycloalkene they added to which flask and they are not sure which was which. They analyzed the Ric which toid them both reaction went to completion. They have to come you for your help to sort out the problem because they know you are awesome at Organic Chemistry

You tell them to use IR to sort out which reaction is which. They run the IR and they tell you that they had these peaks.

Flask labelled Oxidative Cleavage $1$ : $1$ peak at $1705cm-1($s$)$ and $1$ peak at $1725cm-1($s$).$ Additionally they are seeing a peak at $2750cm-1(m).$ They are also seeing some strong peaks between $2800-3000cm-1.$

Flask labelled Oxidative Cleavage $2$ : $1$ peak at $1710cm-1(s)$ and $1$ peak at $1715cm-1($s$).$ They are also seeing some strong peaks between $2800-3000cm-1.$

Reactions: Indicate on the products which finctional groups produced which IR peals above.

$1-$ethy$-2-$rethyicyctohex$-1$ene

$1-$athylcyclchox$-$t$-$ene

dimethydsulide

$0_3,(78C)$

dimebrybaitde

manang$-2,7-$dione

E$-$excoctanai

ANSWER: Which alkene was added to which Oxidative Cleavage Flask?

Oxidative Cleavage I :

Oxidative Cleavage $2$
