Question 1
1 / -0

In the reaction,
$$CH_{3} - CH = CH - CHO \underset {alkaline}{\xrightarrow {Oxidizing\ Agent}}CH_{3}- CH = CH - COOH$$, the oxidizing agent can be:

A
alkaline $$KMnO_{4}$$

B
acidified $$K_{2}Cr_{2}O_{7}$$

C
Benedict's solution

D
all of the above
Question 2
1 / -0

Oxidation of cyclohexene in presence of acidic potassium permanganate leads to.

A
Glutaric acid

B
Adipic acid

C
Pimelic acid

D
Succinic acid

Solution

Oxidation of cyclohexene in presence of acidic potassium permanganate leads to Adipic acid.
Adipic acid is hexanedioic acid. The C=C double bond in cyclohexene is broken and the C atoms attached to double bond are oxidised to $$ \displaystyle -COOH$$ groups.
Question 3
1 / -0

Which of the following compound upon oxidation gives isophthalic acid?

A
p-Xylene

B
m-Xylene

C
o-Xylene

D
m-Cresol
Question 4
1 / -0

Trichloroacetaldehyde, $$ CC{ l }_{ 3 }CHO$$ reacts with chlorobenzene in presence of sulphuric acid and produces:

A

B

C

D

Solution

From the above reaction trichloroacetaldehyde $$C{ Cl }_{ 3 }CHO$$ reacts with chlorobenzene in presence of Sulphuric acid produces DDT
Hence option D is correct answer.
Question 5
1 / -0

Which of the following is not a final product obtained by cross aldol condensation of ethanal and propanal?

A
3-Methyl-but-2-enal

B
2-Methyl-pent-2-enal

C
But-2-enal

D
Pent-2-enal

Solution

3-Methyl-but-2-enal is not a final product obtained by cross aldol condensation of ethanal and propanal.
Question 6
1 / -0

Which is the main functional group in Acrolein?

A
Aldehyde

B
Alkene

C
Nitrile

D
Ester

Solution

Aldehyde $$( \displaystyle -\underset { \displaystyle \underset { \displaystyle O}{ || } }{ C}-H )$$ is the main functional group in Acrolein.
Question 7
1 / -0

In the given reaction sequence :

A

B

C

D

Solution
Question 8
1 / -0

Among the following sets of reactants, which one produces anisole?

A
$$CH_{3}CHO; RMgX$$

B
$$C_{6}H_{5}OH; NaOH; CH_{3}I$$

C
$$C_{6}H_{5}OH; neutral\ FeCl_{5}$$

D
$$C_{6}H_{5} - CH_{3}; CH_{3}COCl; AlCl_{3}$$

Solution

The above reaction is the preparation of Anisole phenol$$+NaOH+C{ H }_{ 3 }I$$ gives anisole. $${ C }_{ 6 }{ H }_{ 5 }OH, \ NaOH, \ C{ H }_{ 3 }I$$ is the correct answer.

1 / -0

Identify the structure of $$M$$ in the following sequence of reactions.

A

B

C

D

A
$${ CH }_{ 2 }=CH-CHO$$

B
$${ CH }_{ 2 }=CH-CN$$

C
$${ CH }_{ 2 }=CN-COOH\quad $$

D
$${ CH }_{ 2 }=CH-CO{ NH }_{ 2 }$$

Solution

Acrolein - $$C{ H }_{ 2 }=CH-CHO$$
