Assertion : t-Butyl methyl ether is not prepared by the reaction of t-butyl bromide with sodium methoxide.
Reason : Sodium methoxide is a strong nucleophile.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.

Assertion : Molar entropy of vaporisation of water is different from ethanol.
Reason : Water is more polar than ethanol.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false.
Which of the following statements is not true about alcohols?
Lower alochols have fiery taste and strong smell.
As molecular mass increases the boiling point increases.
Lower alcohols are water insoluble and their solubility increases with molecular weight.
Lower alcohols are water soluble and their solubility decreases with molecular weight.
Assertion: o-Nitrophenol is more volatile than p-nitrophenol.
Reason : Intramolecular hydrogen bonding is present in o-nitrophenol while intermolecular H - bonding is in p-nitrophenol.
If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
If Assertion is true but Reason is false.
If Assertion is false but Reason is true.
A.
If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
p-Nitrophenol has higher boiling point than o-nitrophenol, because intermolecular hydrogen bonding present in p-nitrophenol is responsible for it. But intramolecular hydrogen bonding in o-nitrophenol does not effect boiling point.
Assertion: Phenol is a weaker acid than ethanol.
Reason: Groups with +M effect and -I effect decrease acidity at m-position.
If both assertion and reason are true and reason is a correct explanation of the assertion.
If both the assertion and reason are true but the reason is not a correct explanation of the assertion.
If the assertion is true but the reason is false.
If both the assertion and reason are false.
