No such resonance is possible therefore stability of alkoxide is less than phenoxide as a result phenol has more tendency to form phenoxide ion due to which phenol is more acidic than alcohols. In this chapter, students learn about preparation, properties and various reactions of alcohols, phenols, and ethers. 1. If electron withdrawing group is present at ortho or para position like  NO2 , CN , Cl etc then  they disperse  this negative charge and will enhance acidic strength, whereas if electron donating group’s like CH3, alkyl group, NH2 (amine) or OR etc are present they decrease the acidic strength. Please note: If we want to stop the reaction at stage of aldehyde, we can use mild oxidizing agent. Because in alcohol it is sp 2 hybridised in phenol and Sp 3 hybridised C atom in alcohol. As compared with alcohol, phenol is more acidic than alcohol. Alcohols and phenols can be classified as primary, secondary or tertiary.
