Assertion: Boiling points of alcohols and ethers are high. Reason: They can form intermolecular hydrogen-bonding.

Melting and boiling points of ionic compounds are high.

True of False: Sulphuric acid has high boiling point and a high viscosity because it forms intramolecular hydrogen bonding.

Give reasons : Boiling point of alkyl bromide is higher than alkyl chloride.

The Boiling Point of ethers are lower than isomeric alcohols why ?

Assertion: The value of van der Waals constant a is larger for ammonia than for nitrogen. Reason: Hydrogen bonding is present in ammonia.

Assertion : Polyamides are best used as fibres because of high tensile strength. Reason : Strong intermolecular forces (like hydrogen bonding within polyamides) lead to close packing of chains and increase the crystalline character, hence, provide high tensile strength to polymers.

Why are the boiling points of carboxylic acids higher than the corresponding alcohols ?
