Given below are two statements:
Statement I.  In Lucas test, primary, secondary, and tertiary alcohols are distinguished on the basis of their reactivity with conc. \(HCl + ZnCl_2\), known as Lucas Reagent. 
Statement II. Primary alcohols are most reactive and immediately produce turbidity at room temperature on reaction with Lucas Reagent. 
In light of the above statements, choose the most appropriate answer from the options given below:
1. I is incorrect but II is correct 
2. Both I and II correct 
3. Both I and II are incorrect

Given below are two statements:
I: The acidic strength of monosubstituted nitrophenol is higher than phenol because of electron withdrawing nitro group.
II: o-Nitrophenol, m-nitrophenol and p-nitrophenol will have same acidic strength as they have one nitro group attached to the phenolic ring.

1. I is incorrect but II is correct.
2. Both I and II are correct.
3. Both I and II are incorrect.
