**Question 4: Diels-Alder Reaction and Dienes Identification**For the following dienes A-G, please circle which organic molecules would **not** function as dienes in a Diels-Alder reaction:**Diagram/Structures Provided:**- **Molecule A:** Structure resembling 2,3-dimethyl-1,3-butadiene (a conjugated diene with two double bonds separated by a single bond)- **Molecule B:** Structure resembling 2,4-hexadiene (a conjugated diene with two double bonds separated by a single bond)- **Molecule C:** Structure resembling cyclopentadiene (a cyclic conjugated diene)- **Molecule D:** Structure resembling 1,3-cyclohexadiene (a cyclic conjugated diene)- **Molecule E:** Structure resembling 1,2-pentadiene (an allenic system with adjacent double bonds, not a conjugated diene)- **Molecule F:** Structure resembling 1,3-pentadiene (a conjugated diene with two double bonds separated by a single bond)- **Molecule G:** Structure resembling propene (an alkene with only one double bond, not a conjugated diene)**Key Concepts:**- **Diels-Alder Reaction:** A chemical reaction between a conjugated diene and a dienophile to form a cyclohexene system.- **Conjugated Diene:** A system with alternating double and single bonds, which is essential for the Diels-Alder reaction.**Instructions:** Examine the given molecules and identify which ones are not suitable to act as dienes in a Diels-Alder reaction based on their structural properties.**Answer Explanation:**- Molecule **E** (1,2-pentadiene) and Molecule **G** (propene) would not function as dienes in a Diels-Alder reaction. Molecule **E** is an allenic system with two adjacent double bonds and Molecule **G** has only one double bond, neither of which meets the criteria to participate in a Diels-Alder reaction as a diene.

For a diene in Diels Alder reaction, it should be in cis form and conjugated. If a diene is in trans…

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.
