Variety of products are obtained when dicarboxylic acids are heated. The nature of product depends on the carbon chain length seperating the two carboxylic groups.
(I) 1 ,2 and 1,3-dibasic acids on heating give monocarboxylic acid
(II) 1,4 and 1,5-dibasic acids on heating give cyclic anhydride
(III) 1,6 and 1,7-dibasic acids give cyclic ketones.
Indicate whether the following reactions are right or wrong.

Which of the following dicarboxylic acids gives a cyclic anhydride on heating?

Which of the following dicarboxylic acids gives a cyclic anhydride on heating?

Dicarboxylic acids have two carboxylic groups, e.g., Acidity of dicarboxylic acid depends upon the stability of intermediate ion and upon the distance between two carboxylic groups. Shorter the distance between two carboxylic groups, greater is the acidic character. Melting point of these acids depends on the symmetry. Greater the symmetry, higher will be the melting point. Dicarboxylic acids on heating give monocarboxylic acid allkanes, cyclic ketones depending on the conditions Which of the following dicarboxylic acids, will give monocarboxylic acid on heating ?

Dicarboxylic acids on heating give monocarboxylic acid, alkanes, cyclic ketones depending on the conditions Which of the following dicarboxylic acids is used in the manufacture of nylon-66?

Dicarboxylic acids have carboxylic groups e.g. HOOC-COOH,oxalic acid HOOC -CH_(2)- COOH-Maloic acid HOOC- (CH_(2))_(3) -COOH-Glutaric acid HOOC, (CH_(2))_(4) -COOH,-Adipic acid Acidity of dicarboxylic acids depends upon the stabillity of intermediate ion and upon the distance between two carboxylic groups. shorter the distance between two carboxylic groups, greater is the acididc character. Melting point of the acids depends on the symmetry. greater the symmetry, higher will be the mp. Dicarboxylic acids on heating give monocarboxylic acid, alkanes, cyclic ketones dependings on the conditions. Which of the following dicarboxylic acid is used in the manufactures of nylon-6,6?

Ques no. 1: Cumene on air oxidation give 1) carbonic acid 2) Carbolic acid 3) carboxylic acid 4) oxalic acid
