Answer 1

Answer:

Explanation:

For molecules having conjugated systems of electrons, the ground states and excited states of the electrons are closer in energy than for nonconjugated systems. This means that lower energy light is needed to excite electrons in conjugated systems, which means that lower energy light is absorbed by conjugated systems.Fundamentally, absorption of ultraviolet and visible radiation comes about as the result of transitions of valence shell electrons between different energy levels. ... The answer is tied up in the bonding and non-bonding electrons within the molecules that comprise the compounds.
