A
$$1,4-$$butanedioic acid

B
Dimethyl$$-2-$$acid

C
$$1,2-$$dimethyldioic acid

D
None of these

Solution

The IUPAC name of succinic acid is 1,4−butanedioic acid.

$$\overset { 1 }{ C}OOH -\overset { 2 }{ { CH }_{ 2 }- } \overset { 3 }{ { CH }_{ 2 }- } \overset { 4 }{ C}OOH $$

$$1,4-$$ $$\text{butanedioic acid}$$

A
Electrophilic addition

B
Nucleophilic substitution

C
Nucleophilic addition

D

1 / -0

Write the $$IUPAC$$ name of $$CH_3CH_2COOH.$$

A
Ethyl formic acid

B
Ethyl carboxylic acid

C
Ethane methanoic acid

D
Propanoic acid

Solution

$$\begin{matrix} \underset { 3 } { CH _ 3 } - \underset { 2 }{ { CH }_{ 2 } } - \underset { 1 }{ COOH } \\ & & \end{matrix}$$
Propanoic acid
Question 6
1 / -0

Which one is called ethanoic acid

A
$$HCOOH$$

B
$$CH_3COOH$$

C
$$CH_3CH_2COOH$$

D
$$CH_3CH_2CH_2COOH$$

Solution
Question 7
1 / -0

To get DDT , chlorobenzene has to react with which of the following compounds in the presence of concentrated sulphuric acid

A
Trichloroethane

B
Dichloroacetone

C
Dichloroacetaldehyde

D
Trichloroacetaldehyde

Solution

trichloroacetaldehyde reacts with chlorobenzene in the presence of conc. $$H_2SO_4$$ to produce DDT.
Hence option D is correct
Question 8
1 / -0

The above reaction is

A
Electrophilic substitution

B
Electrophilic addition

C
Nucleophilic addition

D
Nucleophilic substitution

Solution

$$\text{It is an example of nucleophilic addition reaction}$$
Question 9
1 / -0

The most acidic of the following is

A
$$ClCH_2COOH$$

B
$$C_6H_5COOH$$

C
$$CD_3COOH$$

D
$$CH_3CH_2COOH$$

Solution

Any electron-withdrawing substituent (having$$'-I-effect$$) stabilises the anion by dispersing the negative charge and therefore, increases the acidity. Chlorine is an electron-withdrawing group.

Acid Chloride > Acid Anhydride > Ester > Amide.

B
Acid Chloride > Amide > Acid Anhydride > Ester

C
Amide > Acid Anhydride > Ester > Acid Chloride

D
Ester > Acid Chloride > Acid Anhydride > Amide.

Solution
