Aldehydes and ketones on mild reduction give primary and secondary alcohols respectively. This type of reduction is carried out either catalytically with H 2 in the presence of Ni, Pt or Pd or chemically by LiAlH 4 (Lithium Aluminium Hydride) or NaBH 4 (Sodium boro..

Aldehydes and Ketones react with ammonia in the presence of reducing agents such as H 2 /Raney Nickel or Sodium cyano borohydride (NaCNBH 3 ) to give primary amines. The reaction proceeds through the formation of imines which gets further reduced to give amine..

Alkenes react with ozone to form ozonides which on subsequent reductive cleavage with zinc dust and water or H2/Pd give aldehydes, Ketones or a mixture of both depending on the substitution pattern of the alkene. ..

Reaction with Carbonyl Compounds - Primary amines react with aldehydes and ketones to yield imines also called Schiff base..

Alcohols and Phenols are compounds containing -OH as the functional groups. In alcohols, the -OH group is attached to sp 3 hybridised carbon. In phenols, it is attached to sp 2 hybridised carbon of an aromatic ring. In ethers, oxygen atom is attached to two carbons atoms by two separate sigma bonds..

RCN and RNC are metamers of each other. Alkyl cyanides are prepared from alkyl halides treatment with alcoholic KCN. Alkyl isocyanides are prepared from alkyl halides using alcoholic AgCN. Lower cyanides are soluble in water while isocyanides are insoluble. RCN on partial hydrolysis prod..

Aldehydes, ketones, carboxylic acids and their functional derivatives (aryl halides, acid anhydrides, esters and amides) contain a carbonyl group and are highly polar molecules. They boil at higher temperature than hydrocarbon and weakly polar compounds like ethers, of comparable mo..

(i) By ozonolysis of alkenes Alkenes react with ozone to form ozonides which on subsequent reductive cleavage with zinc dust and water or H 2 /Pd give aldehydes, Ketones or a mixture of both depending on the substitution pattern of the alkene. (ii) By hydration of alkynes E..
