This question is primarily based on the Cannizzaro reaction, where a base induces a disproportionation reaction of non-enolizable aldehydes (benzaldehyde, formaldehyde, etc) to form an alcohol and a carboxylic acid.
In the video by Nile Red exploring the Cannizzaro reaction (https://www.youtube.com/watch?v=qEBC204WTKs), the product mixture contained both Benzoic acid and Benzyl alcohol and had an orange color. I am aware that the benzoic acid was in the form of sodium benzoate due to sodium hydroxide also reacting with the acid produced.
My question is, where does the colour come from?
I am guessing it is either from the benzyl alcohol or sodium benzoate, but I have learned that most organic compounds are colorless.
Moreover, if the aldehyde used was something like formaldehyde, will the orange color also form?
Thanks in advance for the clarifications.
