Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

A company with low gearing is one that is mainly being funded or financed by share capital (equity) and reserves‚ whilst the one with a high gearing is mainly funded by loan capital. Now the question to address is which of the two (equity and debt) is cheaper to the company? The answer is that cost of debt is cheaper than cost of equity. This is because debt is less risky than equity and the tax advantage of debt over equity as discussed below: Risk: debt is less risky than equity because: • the

DNA‚ which stands for Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. These nucleic acids consist of long chains if chemical units called nucleotides. Nucleic acids are information storage molecules that provide the directions for building proteins. Described by the DNA testing centre‚ Inc.‚ “DNA is found inside the chromosome
