Pinacol was converted to pinacolone in the experiment at a 15.60% yield. A low percent yield was expected due to the experimental distillation and experimental separation of the two layers. Some pinacolone could have been trapped in the aqueous layer due to experimental error at separating via a pipet. The IR showed peaks at 2967‚ 2906‚ 2871‚ 2359‚ 2337‚ 2173‚ and 1989. The representative peaks in an IR of pinacolene are present between 3000 and 1700. The NMR when manipulated with a multiple of three

Introduction The primary function of the heart is to transport blood throughout the body‚ which delivers oxygen‚ nutrients and chemicals to the cells of the body to ensure their survival and proper function and to remove the cellular wastes. For the body to achieve this‚ it must maintain a certain blood pressure within the body to overcome gravity and orthostatic changes. If the body did not keep a certain pressure‚ distal cells and organs would not be able to receive a constant blood supply and

Investigating the Growth of P. fluorescens Biofilms at the Air-Liquid Interface and the Variations in Biofilm Integrity Abstract Pseudomonas fluorescens produces biofilms in a variety of environments‚ and in experimental situations has been shown to develop random mutations resulting in a phonotypical change in the resulting biofilm. One particular mutation resulted in the growth of a biofilm known as the Wrinkly Spreader‚ which produced a thicker‚ stronger biofilm that had a stronger attachment

Digital Computers There are two distinct families of computing device available to us today‚ the all pervasive digital computer and almost forgotten analog computer. These two types of computer operate on quite different principles. Digital computer operates on digital data such as numbers and proceeds in discrete steps from one state to next. It uses binary number system in which there are only two digits 0 and 1. Each one is called a bit. The digital computer is designed using digital circuits
