Interpretation:
The formula of the molecule that is formed by the covalent bonding of three atoms with an electronic configuration of
Concept introduction:
The forces which initiates the interaction between the atoms of a molecule is known as the intermolecular forces. The intermolecular forces are of two types; forces of attraction and forces of repulsion. The name of the intermolecular forces are, ion-dipole forces of attraction, vanderwaal’s forces, hydrogen bonding, dispersion forces and others.
The partial electrostatic forces of attraction that exists between hydrogen atom and any bonded electronegative atom like oxygen atom is known as hydrogen bonding.

- Bond Enthalpy When atoms of the hypothetical element X are placed together, they rapidly undergo reaction to form the X2 molecule: X(g)+X(g)X2(g) a Would you predict that this reaction is exothermic or endothermic? Explain. b Is the bond enthalpy of X2 a positive or a negative quantity? Why? c Suppose H for the reaction is 500 kJ/mol. Estimate the bond enthalpy of the X2 molecule. d Another hypothetical molecular compound, Y2(g), has a bond enthalpy of 750 kJ/mol, and the molecular compound XY(g) has a bond enthalpy of 1500 kJ/mol. Using bond enthalpy information, calculate H for the following reaction. X2(g)+Y2(g)2XY(g) e Given the following information, as well as the information previously presented, predict whether or not the hypothetical ionic compound AX is likely to form. In this compound, A forms the A+ cation, and X forms the X anion. Be sure to justify your answer. Reaction: A(g)+12X2(g)AX(s)The first ionization energy of A(g) is 400 kJ/mol.
