Are hydrogen bonds formed between all molecules?1.) No because hydrogen can only form these bonds with oxygen atoms.
2.) No because hydrogen can only form these bonds with highly electronegative atoms.
3.) Yes because hydrogen can easily form bonds with atoms that have a neutral charge.
4.) Yes because hydrogen can form these bonds with weakly electronegative atoms.

The correct statement for the given problem is
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 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 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 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 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.

No, hydrogen can only form these bonds with highly electronegative atoms. Therefore, the correct option is option 2.
When an electronegative atom is attracted to another electronegative atom nearby, a hydrogen atom that is covalently bound to a highly electronegative atom forms a hydrogen bond. This attraction results from variations in electronegativity values, which unbalances the distribution of electrons. While the electronegative atom acquires a partial negative charge, the electron-deficient hydrogen becomes weakly positively charged. The electromagnetic attraction between these partially positive and partially negative ions is known as a hydrogen bond, and it is quite powerful.
Therefore, the correct option is option 2.

An endothermic reaction refers to a reaction in which heat taken in. This implies that heat is usually absorbed by the reaction system. The enthalpy of reaction for an endothermic reaction is always positive.
The triple bond between two Nitrogen atoms in N2 gas is very strong due to its small size and the triple bond thus the nitrogen molecule has a high dissociation energy. This accounts for the large amount of energy required to break the triple bond between nitrogen atoms in the nitrogen molecule. This causes the oxidation of Nitrogen molecule to NO to be largely endothermic.
