1.	How will you distinguish between : (i) Diethyl ether and Propanol.(ii) Formic acid Acetic acid(iii) Formaldehyde and Acetaldehyde
Answer» Solution :(i) PROPANOL produces hydrogen (bubbles) when reacted with SODIUM. Ether does not react with sodium. (ii) Formic acid responds to following TEST whileAcetic acid does not give any of them (a) Formic acid `+` Fehling's solution `rarr` Silver mirror (b) Formic acid `+` Fehling's solution `rarr` red ppt. (iii) ADD `I_(2)` and `NaOH` : Formaldehyde will not react WHEREAS Acetaldehyde gives yellow ppt. due to iodoform.
