Answer the question on the basis of passage given below:
Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric and electronic reasons. Sterically, the presence of two relatively large substituents in ketones hinders the approach of nucleophile to carbonyl carbon more than aldehydes having only one such substituent Electronically aldehydes are more reactive than ketones because two alkyl groups reduce the elctrophilicity of the carbonyl more effectively than in former.

Match List I with List II

List I	List II
	I. \(CrO_3 / H_2SO_4\)
	II. \(H_3O+ / \Delta\)
	III. Ammonical silver nitrate
	IV. \(KMnO_4- H_2SO_4/\Delta\)

Choose the correct answer from the options given below:

A-III, B-IV, C-I, D-II

The correct answer is option 2. A-III, B-IV, C-I, D-II.

List I	List II
	III. Ammonical silver nitrate
	IV. \(KMnO_4- H_2SO_4/\Delta\)
	I. \(CrO_3 / H_2SO_4\)
	II. \(H_3O+ / \Delta\)

Let us look at each of the given reaction in details:

Ammonical silver nitrate is also known as Tollen's reagent. Tollens’ test, also known as silver-mirror test, is a qualitative laboratory test used to distinguish between an aldehyde and a ketone. It exploits the fact that aldehydes are readily oxidized (see oxidation), whereas ketones are not. Tollens’ test uses a reagent known as Tollens’ reagent, which is a colorless, basic, aqueous solution containing silver ions coordinated to ammonia \([Ag(NH_3)^{2+}]\). It is prepared using a two-step procedure.

Oxidative cleavage using potassium permanganate \((KMnO_4)\) in the presence of sulfuric acid \((H_2SO_4)\) and heat is a powerful method for breaking carbon-carbon double or triple bonds in organic molecules, leading to the formation of carboxylic acids, ketones, or carbon dioxide, depending on the structure of the substrate. When an alkene is treated with hot, acidic potassium permanganate, the double bond is cleaved, and the two carbon atoms of the double bond are oxidized. If the carbon is attached to hydrogen, a carboxylic acid is formed. If the carbon is attached to another carbon, a ketone or another carboxylic acid can result.

Chromic acid, \(H_2CrO_4\), is a strong acid and a reagent for oxidizing alcohols to ketones and carboxylic acids. For fairly mundane reasons owing primarily to safety and convenience, chromic acid tends to be made in the reaction vessel as needed (through addition of acid to a source of chromium), rather than being dispensed from a bottle. Choosing a source of chromium to make \(H_2CrO_4\) from is a lot like choosing a favorite brand of bottled water. Beyond the packaging, they’re pretty much all the same. The key point is that \(Na_2CrO_4\) (sodium chromate), \(Na_2Cr_2O_7\) (sodium dichromate), \(K_2CrO_4\) (potassium chromate), \(K_2Cr_2O_7\) (potassium dichromate), and \(CrO_3\) (chromium trioxide) are all alike in one crucial manner: when they are combined with aqueous acid, each of them forms \(H_2CrO_4\), and ultimately it’s \(H_2CrO_4\) which does the important chemistry.

Once \(H_2CrO_4\) is formed, its reactions are pretty straightforward: it converts primary alcohols (and aldehydes) to carboxylic acids and secondary alcohols to ketones.

It does this through addition of the alcohol oxygen to chromium, which makes it a good leaving group; a base (water being the most likely culprit) can then remove a proton from the carbon, forming a new π bond and breaking the \(O-Cr\) bond.

Amides are carboxylic acid derivatives where the \(–OH\) of the carboxylic acid has been replaced by \(–NH_2\), \(–NHR\), or \(–NR_2\) of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a “condensation reaction”.
