Respuesta :
The correct answer would be the first option. Hydrogen bonds do not form in all molecules because hydrogen can only form these bonds with highly electronegative atoms. It is a weak type of force that happens when a hydrogen atom is bonded to an atom which has a high electronegativity.
The correct statement for the given problem is [tex]\boxed{{\text{2)}}\;{\text{No because hydrogen can only form these bonds with highly electronegative atoms}}}[/tex]
Further Explanation:
Intermolecular forces:
The forces that exist between the molecules are known as intermolecular forces (IMF). IMF includes both attractive as well as repulsive forces. They are electrostatic in nature and determine the bulk properties of the substances like melting and boiling points. Molecules are held in any substance due to these forces.
The various types of intermolecular forces are as follows:
1. Hydrogen bonding:
It is an attractive force that exists between hydrogen and more electronegative elements like N, O, F. It can either be intermolecular or intramolecular. Intermolecular hydrogen bonding is the one that occurs between different molecules. For example, the bond between HF and [tex]{{\text{H}}_{\text{2}}}{\text{O}}[/tex] is an intermolecular hydrogen bond. Intramolecular hydrogen bonding occurs between various parts of the same molecule. Ortho-nitro phenol and salicylaldehyde show this type of bonding.
2. Ion-dipole forces:
It is an attractive force that occurs between an ion and a molecule consisting of a dipole. The force between [tex]{\text{N}}{{\text{a}}^ + }[/tex] and water molecule is an example of this force.
3. Ion-induced dipole forces:
It is an attractive force that occurs between an ion and a nonpolar molecule. It induces a dipole in the molecule, resulting in ion-induced dipole force. The bond between [tex]{\text{F}}{{\text{e}}^{2 + }}[/tex] and oxygen molecule is an example of such kind of bond.
4. Dispersion forces:
Also known as London dispersion forces, van der Waals forces, instantaneous dipole-induced dipole forces. These forces exist between atoms and molecules. The forces that occur in [tex]{{\text{F}}_2}[/tex] molecule is a dispersion force.
(1) Hydrogen bond is the one formed between the highly electronegative atom and hydrogen. Although oxygen is a highly electronegative element, it also forms hydrogen bonds with hydrogen. But it there are also more electronegative elements, other than O that can form hydrogen bonds with hydrogen. So this statement (1) is incorrect.
(2) As is clear from the definition of hydrogen bonds, it is formed between highly electronegative elements (like F, O, and N) and hydrogen. So this statement (2) is correct.
(3) Hydrogen bonding is formed as the result of interaction between and an element that can induce a dipole in hydrogen. But neutral atom cannot induce any charge on hydrogen atom. So this statement (3) is incorrect.
(4) Hydrogen can form bonds with high electronegative elements and not with the weak electronegative elements. So the given statement (4) is incorrect.
