SUMMARY

The absorption spectrum of the 1,3-pentadiene molecule shows a peak absorption at 224 nm, indicating an electronic transition. To estimate the length of the molecule, alternative methods beyond Lambert's law should be considered, as it is not applicable in this context. The discussion emphasizes the need for understanding molecular size in relation to absorption wavelengths.

PREREQUISITES

Summary: The experimentally measured absorption spectrum of 1,3-pentadiene molecule exhibits a
peak absorption (light absorption) around 224 nm corresponding to an electronic
transition. Estimate the length of the molecule.

I thought of using lambert law A = c*l*e but we have none. how do I solve this

This has nothing to do with Lambert's law. What else have you seen that could link the absorption wavelength to the size of the molecule?
