Question

Mark the correct order of decreasing acid strength of the following: (A) V > IV > II > I > III (B) II > IV > III > I > V (C) IV > V > III > II > I (D) V > IV > III > II > I

Tardigrade Admin · Accepted Answer

Electron withdrawing group increase acid strength of alcohol
II -Electron with drawing group-

N O_{2}

at para position impart significant acid strength
IV - NO

_{2}

Group at Meta position exhibit only-I effect,
III - At Meta position exhibit weak-I effect
I -NO-I effect arid no resonance

v

- electron donating group

(OC H_{3})

at Para position decrease acid strength
