4-nitro phenol>phenol>4-methyl phenol a is more acidic than b and c because In a No2(Nitro group) being a electron withdrawing group it withdraws the electron density thus increase the acidity Or in case of B Ch3 being a electron donating group it donates the electron density thus decreases the electron density Order of lucas test 3⁰>2⁰>1⁰
17:07 A : most acidic ( 4 - nitrophenol) Reason - due to pesence of electron withdrawing grp ( NO2) which increases acidic character B: least acidic ( 4- methy phenol) Reason - due to the presence of electron donating group( CH3) which decreases the acidic character

Phenol does not react with hx px, px3 ,PCL5 and Socl2 because phenol is highly stable due to the phenomenon called resonance where delocalisation of electron takes place

For Lucas test the reactivity order of alcohols are 3>2>1 As 3 degree alcohol will show turbidity in seconds , 2 degree alcohol will show turbidity in minutes , 1 degree alcohol will show turbidity in hours and many 1 degree alcohol don't show turbidity even after long periods so we have to heat them for there fast rxn .
