Dear Anmol,


Acidic strength is mainly the ability to release a proton in a reaction. More stable the resulting product after deprotonation, the more stronger the acid is.

So, the order you asked will be like this,

Ethers<Ketones<Aldehydes<Alcohols<Phenols<Carboxylic Acids


Carboxylic acids & phenols are stabilised by resonance delocalisation of charge after deprotonation. So they're the stronger ones.
