The correct increasing order of the acidic strength of acids, butyric acid (I), 2-chlorobutyric acid (II), 3-chlorobutyric acid (III) and 2, 2-dichlorobutyric acid (IV) is
I < II < III < IV
III < II < IV < I
I < III < II < IV
III < I < II < IV
C.
I < III < II < IV
Among the given list of acids, the acidic strength increases on-
(i) Presence of electron with drawing group (i.e. - I group)
(ii) Closeness of electron withdrawing group from the -COOH group.
(iii) Number of electron with drawing groups (i.e. -I group)
Hence, the correct order among the given options will be I < III < II < IV

(III) CH3CH2CH2Cl and
(IV) Towards SN2 displacement is
I < II < III < IV
III < I < IV < II
III < I < II < IV
II < IV < I < III
