Let's start with cross aldolChemistry Level 3
A bit of info
A cross aldol reaction is a aldol reaction between 2 different aldehydes (or even ketones).
The situation you are stuck with
You have \(n\) aldehydes (all of them \(DISTINCT\) ) with you on your lab desk, and a large container having \(dil.\) \(NaOH\) in front of you. Without your knowledge you pour all the \(n\) aldehydes into the large container with the alkali.
Lets make it hypothetical
Now you have to find the no. of all possible \(CROSS\) aldol condensation products that takes place between these aldehydes.
Note: DO NOT consider stereoisomers
all substituents have atleast one alpha-hydrogen.
Feel this is easier , then try this problem
