sir/madam,   1. in NCERT chemistry books in organic chemistry sometimes hydrolysis rxn takes places by acid and water(H2SO4 + H2O/ H3O+/H+ + H2)), base with water(NaOH + H2O/ KOH + H2O) and other times only with water(H2O) what is the difference between the three and when do we use them in rxns ? hydrolysis means breaking or cleavage of compounds using water.... am I right?  2. Is Aldol rxn and condensation only limited to 2 molecules of same aldehyde compound and 2 molecules of same ketone compound? then does it mean that it undergoes self condensation? And cross Aldol rxn and condensation is carried out by two different molecules of aldehydes and two different molecules of ketones. is cross Aldol rxn and condensation also carried out between one aldehyde and one ketone molecules? request u to plz answer all questions
