A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding

developed economies of the world. It is important to take a holistic view of the prevailing policy framework covering generic drugs globally‚ making it possible to analyze the effects of these policies on the generic pharmaceutical industry. The first pertinent area of global pharmaceutical policy is funding of research in life sciences. This pertains primarily to reference drugs rather than generic drugs. Globally‚ there is no overarching framework for the same. This is primarily done only in the
