1.1 Background of the Study
Chemistry is one of the three main branches of pure science, others being biology and physics. Chemistry has been defined differently by various authors. Ababio (2004), defined chemistry as the branch of science that deals with the composition, properties and uses of matter. It probes into the principles governing the changes that matter undergoes. Encyclopedia (2015), chemistry is a branch of science concerned with the properties, composition, and structure of substances and the changes they undergo when they combine or react under specified conditions. Furthermore, chemistry can be characterized and studied under its varying branches; organic, inorganic, physical, analytical, industrial, nuclear.
Organic chemistry in its simplest term is the chemistry of carbon compounds, excluding carbon oxides, metal carbonyls, metallic carbonates and other related compounds (Inikori, 2012). Organic chemistry is the chemistry of hydrocarbon and its derivatives (Omwirhiren, 2016). Organic compounds are any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen (Encyclopedia Britannica, 2015).
