Answer»

Solution :(a) Hydrogen of methylene GROUP will be most acidic.
`CH_(3)-underset(**)CH_(2)-OVERSET(O)overset(||)C-underset(**)CH_(2)-CH_(3)`
(b) In this compound, allylic hydrogen will be most acidic.
`H_(2)C=CH-underset(**)CH_(2)-overset(O)overset(||)C-H`
(c ) Hydrogen of methylene group will be most acidic.
`CH_(3)-overset(O)overset(||)C-O-underset(**)CH_(2)-CH_(3)`
(d) Hydrogen of carboxylic group will be most acidic.
`CH_(3)-overset(OH)overset(|)"CH"-overset(O)overset(||)C-Ounderset(**)H`
