Prejudice and Discrimination Article Traveling had always been something I looked forward to. Seeing other parts of the world‚ visiting other countries; just the idea of it brought more joy then most things would. Sadly though‚ that is not the experience that I encountered while travelling to South Africa. Even though it was their native land‚ the locals in South Africa faced an overwhelming amount of discrimination; it was completely heart breaking to witness. Taking into the history of South

containing OH- when it is a substituent in an organic compound. It is also known as the characteristic functional group of alcohols and phenols. On the other hand‚ carbonyl group refers to a divalent chemical unit consisting of a carbon and an oxygen atom connected by a double bond. It is known as the characteristic functional group of aldehydes and ketones instead. In this experiment‚ hydroxyl- or carbonyl- containing samples were given to the group for examination. The samples were analyzed through
Premium Alcohol Aldehyde Functional group
in a very acidic environment‚ the alcohol group is converted into water‚ which is a weak base‚ and thus a good leaving group. Due to lack of steric interference‚ the primary carbon atom is now open to back-side attack. The bromide ion‚ which acts as the nucleophile attacks from the back-side and bonds to the carbon atom. As a result‚ 1-bromobutane is formed and water is given off as the leaving group. SN1 Reaction Mechanism: The reactions that take place in the second part of the experiment all

UNIVERSITY OF THE GAMBIA LECTURE NOTES COURSE: PRINCIPLES OF CHEMISTRY II (ORGANIC CHEMISTRY) CODE: CHM 161 2ND SEMESTER SESSION: 2012/2013 LECTURER: ANTHONY F. ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements
