carbonyl compounds is useful in reactions because nitriles are versatile functional groups1. Not only are they versatile functional groups but they serve as precursors in several transformations. The cyano-group is found in many bioactive molecules and plays a role in hydrogen bonding to certain biological receptors.4 Nitriles are carboxylic acid derivatives because they can easily be converted to carboxylic acid under either basic or acidic conditions. Piperonal is an aromatic compound that is present

this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons. We used the sciatic Lithobates pipiens nerve in this

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

Describe a mingle activity you might create for a new class of intermediate level students to help them introduce themselves to each other. The best way to help students mingle with each other and enhance their proficiency in the English language is by using ice-breaker activities. This effectively encourages the participants to interact with each other freely. An activity which might be done is a ‘getting to know you’ activity where the participants will be given a certain period of time to gather

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the
