Compounds having the same number of carbon atoms follow the boiling point order as:
\((\text{Boiling point})_{\text{Hydrogen bonding}} > (\text{Boiling point})_{\text{High polarity}} > (\text{Boiling point})_{\text{Low polarity}} > (\text{Boiling point})_{\text{Non-polar}}\)
The product (P) formed in the following reaction is:
