Which of the ...

Question

Which of the following statement is true regarding esterification of a carboxylic with an alcohol ?

(i) It is carried out in presence of a strong acid which acts as a catalyst.

(ii) The strong acid makes the carbonyl carbon more electrophilic, and hence causes the alcohol, a strong nucleophile to attack on the carbonyl carbon.

(iii) The strong acid makes the carbonyl group more electrophilic which is thus attacked easily by an alcohol. a weak nucleophile.

(iv) Esterification can be done even in absence of a strong, acid.

Q. A carboxylic acid ester is prepared commonly by reacting a carboxylic acid with excess of an alcohol in the presence of a small quantity of a strong acid such as

c o n c . H_{2} S O_{4}

as a catalyst. The reaction is reversible and generally the equilibrium constant for the esterification is close to

1

. As it is a reversible reaction, different methods are used to increase the yield of ester. It is established that the mechanism of esterification under such conditions involves initial protonation of the acid followed by the attack of the alcohol as a nucleophile.

Q. Phenols are compounds in which a hydroxyl group is bonded directly to an

s p^{2}

hybridized carbon atom of an aromatic ring. It is more acidic than an alcohol, but less acidic than a carboxylic acid. It is even less acidic than carbonic acid but more acidic than water. Thus, phenol is unable to protonate

H C O_{3}^{-}

anion but easily protonates

O H^{-}

anion. The

O H^{-}

group activates the benzene ring so much that electrophilic substitution takes place readily.

The correct order of acidity of the following substituted phenols is:

Sodium carbonate is a basic salt because it is a salt of
(a) strong acid and strong base
(b) weak acid and weak base
(c) strong acid and weak base
(d) weak acid and strong base

Q. Esterification ( shown below ) is a reaction converting a carboxylic acid to its ester. It involves only the carbonyl carbon. Esterification of

(-) -

lactic acid with menthol yields

(+) -

methyl lactate. Assuming that there are no side reactions, what is true about this reaction ?

Q. Choose the correct from the following:
(i) Salt of a strong acid and a strong base are neutral with pH value of 7.
(ii) Salt of a strong acid and a weak base are basic with pH value more than 7.
(iii) SaIt of a weak acid and a strong base are acidic with pH value less than 7.
