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 .

17:11
(a). Para-nitrophenol is more acidic than 4- methyl phenol because in this No2 is an E.W.G which increases acidic strength.
17:09 p-nitrophenol>phenol>p-cresol
29:20 No as there is no methyl group
32:22 3>2>1

17:04 A>C>B p-nitrophenol>phenol/hydroxybenzene> 4 methylhydroxybenzene
17:00 - When nitro group is in the para position, the resulting phenol is most acidic.
17:04 (a) is more acidic because NO2 is present which is E.W.G then (C) the (b) because Ch3 grp is E.D.G which increases basic character
16:44 a>c>b
a= p nitrophenol

Sir please we need separate videos for jee btw your content is awesome for practice fast for exams.
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
Already this content is useful to even neet/jee .
17:09 a) p-nitro phenol> c) Phenol> b) 4 methyl phenol

17:03 High acidic:: 4-Nitrobenzenol

17:00 p-nitrophenol will be the most acidic amongst all 3, since NO2 is electron withdrawing group.

Answer of first question
A>C>B
(Acidic strength)
A: 4-nitro phenol
B: 4-methyl phenol
C: phenol
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
Bhai abhi tum kya kr rhe ho
17:10 =
4-nitrophenol is most acidic due to -I effect of NO2
4-Methylphenol is least acidic due to +I effect of CH3
4-nitrophenol>phenol>4-methylphenol
NO2 group increases acidic strength while CH3 group decreases acidic strength.
