Question

Q1) Let's say that a sample contained 2,4-Hexadiene (among other chemicals) and an absorption spectrum was taken of it. Which absorption peak corresponds to Hexadiene, assuming that its n electrons behave like particles in boxes (show your work) 350 abs HH 300 320 210 ► 2 (nm)

Answer 1

Chemical formula for 2,4-Hexadiene is C6H10.

A plot of the wavelength of the entire regions against the absorbance of light at each wavelength is the absorption spectrum.

The above absorption band of 2,4-Hexadiene shows the absorption band in the region from around 200-400 nm. For 2,4-Hexadiene, the absorption peak is maximum at 300nm as it's pi-electrons is assumed to behave like particles in boxes.
