IB Chemistry - Intermolecular Bonding Essay:

Write an essay on intermolecular hold fast. rationalise how for apiece cardinal example of bond arises and the evidence for the populace of each. Comment on their strengths in relation to the types of fragments involved; the covalent bond and relative to each other. Use the concepts of different types and strengths of intermolecular bonds to explain the following: There exists quaternity types of intermolecular bonding, they accept ionic, covalent, Van der waals and hydrogen bonding. In club to describe the existence of such bonding you must too understand the concepts of frostyity, polar and non-polar, and electronegativity. Ionic bonds are created by the complete move of electrons from one atom to another(prenominal). In this process of electron transfer, each atom becomes a ion that is isoelectronic with the nearest noble splosh., the substance is held in design by electrostatic forces between the ions. The tendency for these ions to be stimulate by elements i s corespondent to the octet rule, when atoms react,, they tend to do so in such a way that they attain an outer(prenominal)(prenominal) pip containing eight electrons. The factors that effect the brass of ions are ionization energy, electron affinity, lattice energy. Figure 1 The transfer of electrons involved in the formation of (a) sodium chloride and (b) calcium fluoride. Each atom forms an ion with an outer shell containing eight electrons.

For many elements, compounds cannot be formed by the intersection of ions, since the energy released in the formation of the lattice of ions would be deplete d to overcome the energy required to form th! e ions would be insufficient to overcome the energy required to form the ions in the number 1 place. In order for the atoms to achieve a noble gas configuration they must use another method of bonding by the process of electron sharing. From figure...
