# IR Spectral Analysis of Allylcyclohexane Hydrogenation

ORGO1-HGWJAA

A student carried out the hydrogenation of allylcyclohexane, as shown below.​ She isolated the reaction product and took its infrared (IR) spectrum to determine if she had made the desired compound.

What characteristics in the IR spectrum would indicate the reaction had occurred?

Select ALL that apply.

A

Presence of a strong absorbance between 2800 and 3000 ${ cm }^{ -1 }$.

B

Absence of a medium, sharp absorption at 3300 ${ cm }^{ -1 }$.

C

Absence of a medium, sharp absorption at 1640 ${ cm }^{ -1 }$.

D

Presence of a medium, sharp absorption at 1640 ${ cm }^{ -1 }$.

E

Absence of medium, sharp absorbance at 3100 ${ cm }^{ -1 }$.
