Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be

Under the Endangered Species Act in the United States‚ species may be listed as "endangered" or "threatened". The Salt Creek tiger beetle (Cicindela nevadica lincolniana) is an example of an endangered subspecies protected under the ESA. The US Fish and Wildlife Service as well as the National Marine Fisheries Service are held responsible for classifying and protecting endangered species‚ and adding a particular species to the list can be a long‚ controversial process (Wilcove & Master‚ 2008‚ p.

Keystone species play a large role in each ecosystem‚ they have the ability to alter their ecosystem or be the reason they completely collapse. Keystone species are the reason that many different species exist‚ these other species highly depend on the keystone species for survival‚ if a single keystone species were to go extinct‚ it is likely for other species populations to decrease. Other species benefit from keystone species in a variety of ways‚ such as food supply‚ shelter‚ or a water source

is what florida is like now. It’s like this because people let their pet snakes go into the wild and then there are way too many snakes in the wild. Snakes are not the only invasive species there are others like foxes and medfly. Invasive species are a problem‚ but creative solutions are being tested. Invasive species can take over areas of the earth‚ and make it hard for other animals to survive. In Australia they have foxes‚ which are an invasive specie. Foxes are trying to kill penguins‚ because

aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population imbalance‚ predator versus prey imbalance and outright off balancing the entire ecosystem food web. The purpose of this paper is to discuss what an invasive species can do to an ecosystem and possible solutions to correcting the imbalance in the

monkey-eating eagle‚ is an eagle subspecies that belong to the family of Accipitridae and is native to Philippine. These eagle display white-colored plumage together with the shaggy crest‚ averaging 86 – 102 cm (2 ft 10 in to 3 ft 4 in) in length. The weight of these species measure around 4.7 – 8 kg (10 – 18 lb). As far as the eagle’s length is concerned‚ Philippine eagle is the largest‚ harpy eagle and the stellar’s sea eagle being the other contenders. They are also regarded as the rarest and the
