Reactivity of Reagents with HCHO, CH3CHO, and CH3COCH3
To determine which reagent reacts differently with HCHO, CH3CHO, and CH3COCH3, we need to consider the functional groups present in these compounds and the reactions that can occur with different reagents.
HCHO: Formaldehyde (HCHO) contains an aldehyde functional group (-CHO).
CH3CHO: Acetaldehyde (CH3CHO) also contains an aldehyde functional group (-CHO).
CH3COCH3: Acetone (CH3COCH3) contains a ketone functional group (-C=O-).
Now, let's examine the reactivity of the given reagents (HCN, NH2NH2, NHOH, NH) with these compounds.
a) HCN: Hydrogen cyanide (HCN) is a weak acid and can react with aldehydes and ketones to form cyanohydrins. Both HCHO and CH3CHO can react with HCN to form cyanohydrins.
b) NH2NH2: Hydrazine (NH2NH2) is a strong reducing agent and can react with aldehydes and ketones to form hydrazones. Both HCHO and CH3CHO can react with NH2NH2 to form hydrazones.
c) NHOH: Hydroxylamine (NHOH) is a weak base and can react with aldehydes and ketones to form oximes. Both HCHO and CH3CHO can react with NHOH to form oximes.
d) NH: Ammonia (NH) is a weak base and does not react directly with aldehydes or ketones. However, it can undergo a reaction called the Hofmann degradation with primary amides. Since none of the given compounds are primary amides, NH will not react with HCHO, CH3CHO, or CH3COCH3.
Therefore, the correct answer is option 'D' - NH. NH does not react with HCHO, CH3CHO, or CH3COCH3, while the other reagents (HCN, NH2NH2, NHOH) can react with all three compounds.

The reaction with HCHO & NH3=(CH3)6N4.. That is hexamethelene tetramine/hexamine/urotropine...the reaction with CH3CHO & NH3 = acetaldehyde ammonia(CH3CHNH2OH)...and the reaction with CH3COCH3& NH3 gives acetone ammonia..so,there are always available different products.
