Given below are two statements : Statement (I) : p-nitrophenol is more acidic than m-nitrophenol and o-nitrophenol. Statement (II) : Ethanol will give immediate turbidity with Lucas reagent. In the light of the above statements, choose the correct answer from the options given below :

Options

  1. AStatement I is true but Statement II is false
  2. BBoth Statement I and Statement II are true
  3. CBoth Statement I and Statement II are false
  4. DStatement I is false but Statement II is true

Correct answer

A. Statement I is true but Statement II is false

Step-by-step solution

p-Nitrophenol is more acidic than m-nitrophenol and o-nitrophenol. The electron withdrawing group - NO 2 stabilizes phenoxide ion through - R effect at para and ortho position. - NO 2 group in meta position will show - I effect. Presence of - NO 2 group at ortho position it form hydrogen bonding with - OH group. Hence, acidity is less than p-nitrophenol order of acidic strength. Acidic strength Ethanol give lucas test after long time Lucas reagent helps in the distinction of primary, secondary and tertiary alcohols
