Answer 1

Given :  

(i) The 2,4-dinitrophenylhydrazone of benzaldehyde  

(ii) Cyclopropanone oxime  

(iii) Acetaldehyde Dimethyl Acetal  

(iv) The semicarbazone of cyclobutanone  

(v) The ethylene ketal of hexan-3-one  

(vi) The methyl hemiacetal of formaldehyde

The structures of the following derivatives are in the attachment below.

Some important points :  

• In  organic chemistry one of the most important functional groups is carbonyl group containing carbon-oxygen double bond (>C=O) .
• In aldehydes, the carbonyl group is bonded to a carbon and hydrogen.
• In ketones, it is bonded to two carbon atoms.  
• In carboxylic acids the carbonyl group is bonded to carbon or hydrogen and oxygen of hydroxyl .
• In amides and acyl halides carbon is attached to carbon or hydrogen and nitrogen of -NH2 or to halogens .
• In compounds where carbon is attached to carbon or hydrogen and nitrogen of -NH2 moiety or to halogens are called.
• The derivatives of carboxylic acids are Esters and anhydrides.
