Assertion : The water solubility of the alcohols follow the order: t-butyl alcohol > s-butyl alcohol \(>\) n-butyl alcohol Reason : Alcohols form H-bonding with water to show soluble nature.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Alcohols are soluble in water due to hydrogen bonding with water. Solubility increasing with branching. Therefore, tert-butyl alcohol, being the most branched, is the most soluble followed by secondary and primary alcohols. So the option (2) is correct.

Assertion : o-Nitrophenol is less soluble in water than the \(\mathrm{m}\) - and \(\mathrm{p}\)-isomers. Reason : \(\mathrm{m}\) - and p- Nitrophenols exist as associated molecules.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
o-nitrophenol is less soluble in water due to intramolecular H-bonding. \(\mathrm{m}\) - and \(\mathrm{p}\)-nitrophenol exist as associated molecules due to intermolecular H-bonding.

Which of the following would be only very slightly soluble in water?
1 1-Propanol
2 2-Propanol
3 1, 5-pentanediol
4 1-Hexanol
Explanation:
Number of carbon atoms \(\propto \dfrac{1}{\text { solubility }}\)

o-nitrophenol is less soluble in water than \(\mathrm{p}\) - and \(\mathrm{m}\)-nitrophenols because
1 o-nitrophenol shows intermolecular H- bonding
2 o-nitrophenol is more steam volatile than those of \(\mathrm{m}\) - and \(\mathrm{p}\) - isomers
4 Melting point of o-nitrophenol is lower than those of \(\mathrm{m}\) - and \(\mathrm{p}\)-isomers
Explanation:
There is intramolecular \(\mathrm{H}-\) bonding in o- nitrophenol, and thus, solubility in water is decreased.

Assertion : The solubility of alcohols increases with increase in branching. Reason : Ethanol and methanol are immiscible in water.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Ethanol and methanol are miscible in water due to the formation of intermolecular hydrogen bonds between their hydroxyl \((-\mathrm{OH})\) functional groups and water molecules. So the option (3) is correct.
