answered-by-expert Expert Answer
pKa is inversely proportional to the acidic strength, Since pKa = -log Ka
 
Options Name pKa
i Indene 20.1
ii Indole 21
iii 1,3-cyclohexadiene 18
iv Cyclopentadiene 16
 
Thus smaller the value of pKa greater will be the acidic strength - ii>i>iii>iv (decreasing oreder of pKa value)
