Which of the following compounds can be used as antifreeze in automobile radiators?
Methyl alcohol
Glycol
Nitrophenol
Nitrophenol
The reaction of phenol with chloroform in the presence of dilute sodium hydroxide finally introduces, which one of the following functional group?
-CH2Cl
-COOH
-CHCl2
-CHCl2
Given are cyclohexanol (I), acetic acid (II), 2,4,6-trinitropenol (III) and phenol (IV). In these, the order of decreasing acidic character will be
III > II> IV> I
II > III> I > IV
II > III> IV> I
II > III> IV> I
Which one of the following compounds has the most acidic nature?
B.
The presence of electron withdrawing substituent increases the acidity while electron releasing substituent, when present, decrease the acidity.
Phenyl is an electron withdrawing substituent while -CH3 is an electron releasing substituent, Moreover, phenoxide ion is more resonance stabilised as compared to benzoyl oxide ion, thus, release proton more easily. That's why is a strong acid among the given.
Among the following four compounds
A) Phenol
B) Methyl Phenol
C) meta - nitrophenol
D) para-nitrophenol
the acidity order is
D > C > A > B
C > D > A> B
A > D > C > B
A > D > C > B
Consider the following reaction,
the product,Z,is
toluene
benzaldehyde
benzoic acid
benzoic acid
