Assertion : o-Nitrophenol is less soluble in Water than the m-and p-isomers. Reason : m-and p-Nitrophenols exist as associated molecules.

How will you separate a mixture of o-nitrophenol and p-nitrophenol ?

Why does p-dichlorobenzene has a higher m.p. than its o- and p-isomers ?

Give reasons fer the following : o-nitrophenol is more acidic than o-methoxyphenol.

Assertion: p-nitroaniline is a stronger base than p-toluidine. Reason : The electron withdrawing -NO_2 group in p-nitroaniline makes it a stronger base.

Phenols are less acidic than p-nitrophenol. Explain.

These question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following responses If both Assertion and Reason are true and Reason is a correct explanation of Assertion If both Assertion and Reason is a not a correct explanation of Assertion If Assertion is true but Reason is false If both Assertion and Reason are false Assertion: BaCO_3 ​ is more soluble in HNO_3 ​ than in plain water. Reason: Carbonate is a weak base and reacts with the H^+ from the strong acid, causing the barium salt to dissociate.

p-Dichlorobenzene has higher m.p. and lower solubility than those of o and m-isomers. Discuss

The p-isomer of dichlorobenzene has higher melting point than O-and M-isomer. Why ?
