Which of the above compound(s), on being warmed with iodine solution and NaOH, will give iodoform?
A
(i), (iii) and (iv)
B
Only (ii)
C
(i), (ii) and (iii)
D
(i) and (ii)
Explanation
The iodoform test is exhibited by ethyl
alcohol, acetaldehyde, acetone, methyl ketones,
those alcohols which possess CH3CH(OH)— group,
acetophenone, $$\alpha $$-hydroxypropionic acid, keto acid,
2-aminoalkanes, etc.

MCQ (Single Correct Answer)
AIPMT 2010 Prelims
Among the following four compounds
(i) Phenol
(ii) Methyl phenol
(iii) Meta-nitrophenol
(iv) Para-nitrophenol
The acidity order is
A
(iv) > (iii) > (i) > (ii)
B
(iii) > (iv) > (i) > (ii)
C
(i) > (iv) > (iii) > (ii)
D
(ii) > (i) > (iii) > (iv)
Explanation
In phenols, the presence of electron
releasing groups decrease the acidity, whereas
presence of electron withdrawing groups increase
the acidity, compared to phenol.
Among the meta
and para-nitrophenols, the latter is more acidic as
the presence of –NO2
group at para position
stabilises the phenoxide ion to a greater extent than
when it is present at meta position. Thus, correct
order of acidity is :
(iv) > (iii) > (i) > (ii)
