An organic compound A gives positive test with Tollen's reagent on treatment with ammonia forms B which is an eye medicine. A on treatment with concentrated KOH forms C and D . C on oxidation forms A again. D on acidification responds to Tollen's test. A  combines with CH3MgI followed by hydrolysis forms E which on oxidation followed by decarboxylation forms methane. Identify A to E. With proper equations involved.

An organic compound Formaldehyde (A) gives a positive test with Tollen's reagent on treatment with ammonia forms Hexamethylenetetramine (B) which is an eye medicine.
 
 
In cannizarro's condensation, Formaldehyde (A) on treatment with concentrated KOH forms Methanol (C) and Methanoic acid (D). (C) on oxidation forms (A) Formaldehyde again. Methanoic acid (D) on acidification responds to Tollen's test.
 
Formaldehyde (A) combines with CH3MgI followed by hydrolysis forms Ethanol (E) which on oxidation followed by decarboxylation forms methane.

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

sir/madam, is KMnO4-KOH the chemical formula for alkaline potassium permanganate? like in the NCERT if alkylbenzene is reacted with chromic acid (H2CrO4), will there be any intermediate product just like alkylbenzene when reacted with KMnO4-KOH gives potassium salt of carboxylic acid which then further oxidises to carboxylic acid? also is my formula correct for chromic acid and alkaline potassium permanganate? pls requested to respond to all my questions
