Intermolecular Bonding Essay Write an essay on intermolecular bonding. Explain how each type of bond arises and the evidence for the existence of each. Comment on their strengths in relation to the types of atoms 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 four types of intermolecular bonding‚ they include ionic‚ covalent‚ Van der waals and hydrogen bonding. In order to describe

Covalent Bonding In a covalent bond‚ a pair of electrons is shared between two atoms. Each of the positively charged nuclei is attracted to the same negatively charged pair of electrons. The diagram: A and B are held together by this shared attraction. Covalent bonds are often drawn as dots and crosses diagrams to show that the electrons have come from two different atoms. Molecules have a certain fixed number of atoms in them joined together by covalent bonds. Examples: Bonding in hydrogen

Sharing Electrons Example~ A hydrogen atom has one electron. If it had two electrons‚ it would have the same electron configuration as a helium atom. Two hydrogen atoms can achieve a stable electron configuration by sharing their electrons and forming a Covalent bond. A covalent bond is a chemical bond in which two atoms share a pair of valence electrons. When two atoms shair one pair of electrons‚ the bond is called a singe bond.

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements‚ it can be viewed that the three most electronegative elements in the periodical table are nitrogen‚ oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial negative charge while

points? (3 points) Ionic compounds usually have higher melting points. This is because the atoms of covalent compounds are bound strongly to each other in stable molecules‚ but those molecules are in general not very strongly attracted to other molecules in the compound. On the other hand‚ the atoms in ionic compounds show strong attractions to other ions in their vicinity. http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/bond2.html 2.
