Question

The boiling point of a compound is raised by:
(A) Intramolecular Hydrogen bonding
(B) Intermolecular Hydrogen bonding
(C) Covalent bonding
(D) Ionic covalent

Answer 1

Hint: A compound's boiling point is independent of whether it dissolves in water. It does depend on the polarity, size, and interparticle bonding of its molecules.
Complete step by step solution:
As we know that,
Intermolecular hydrogen bonding raises a compound's boiling point. Because larger molecules with more electrons have stronger van der Waals dispersion forces, the boiling point rises as a result.
Intermolecular interactions can affect the melting and boiling temperatures of compounds because they strengthen the bonds between two or more molecules. In general, a substance's melting and boiling temperatures rise along with the strength of the intermolecular force.
Within a single molecule, there are hydrogen bonds known as intramolecular hydrogen bonds. When two functional groups of a molecule are able to make hydrogen bonds with one another, this happens.
Therefore, the correct answer by which the boiling point is raised is Intermolecular Hydrogen bonding.

Hence, the correct option is (B)

Note: Both intramolecular and intermolecular forces can result from hydrogen bonding. The boiling point, melting point and solubilities of isomers containing intra-molecular hydrogen bonds are lower than their isomers showing intermolecular H- bonds.
