ALDEHYDES, KETONES AND CARBOXYLIC ACID

26564 Acetone and acetaldehyde are

1 Position isomers

2 Functional isomers

3 Not isomers

4 Chain isomers

Explanation:

Acetone(ketone, $- C O -$ ) and (aldehyde, $- C H O$ ) are the carbonyl compounds they do not have common isomerism.

ALDEHYDES, KETONES AND CARBOXYLIC ACID

26565 Which of the aldehyde is most reactive $?$

1

C_{6} H_{5} - C H O

2

C H_{3} C H O

3

H C H O

4 All the equally reactive

Explanation:

(c) Among Carbonyl Compounds, reactivity decrease with increase in alkyl groups as alkyl groups ( $+ I$ effect) decrease positive character on C-atom. Thus, the correct order of reactivity is
$H C H O > C H_{3} C H O > C_{6} H_{5} C H O$
