E. Reactions of Aldehydes and Ketones with Sodium Hydroxide Objectives: To know the reactions of aldehydes and ketones with sodium hydroxide a) State the function of Sodium Hydroxide in the test. Sodium hydroxide (NaOH) is the oxidizing agent. b) What are the principles involved in the test? What is its purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol

DISTINGUISHING BETWEEN SCREENING TEST AND DIAGNOSTIC TESTS A diagnostic test is any kind of medical test performed to aid in the diagnosis of detection of a suspected disease or condition. This is different from a screening test which is used when not when a disease or condition is suspected‚ but when people are considered to be at high risk of developing a disease or condition. Diagnostic test are usually performed after a positive screening test to establish a definitive diagnosis. They are

Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson‚ Payton Ewing‚ Lenneisha Hepburn‚ Kendisha Hanna‚ Introduction: Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein‚ starch‚ lipids‚ and sugars by analyzing the content off food

Notes Aldehydes and Ketones The major similarity between an aldehyde and a ketone is the carbonyl group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side

Chemical T ests for Unknowns Chemical tests have been developed as a means of identifying what functional groups are present in an unknown compound. Since IR and NMR spectroscopy has been developed‚ they are no longer critical to unknown analysis‚ but they can still be useful for confirming what you have determined by spectroscopy. Some of them look cool too! In order for a chemical reaction to work as a chemical test‚ it must 1) create a visible result (a color change‚ a precipitate‚ etc)

Esmeralda Curiel Organic Chemistry November 11‚ 2014 Experiment 62 – The Aldehyde Enigma INTRODUCTION In the Cannizaro reaction an aldehyde is simultaneously reduced into its primary alcohol form and also oxidized into it ’s carboxylic acid form. The purpose of this experiment is to isolate‚ purify and identify compounds 1 and 2 which contain 4-chlorobenzaldehyde‚ methanol‚ and aqueous potassium hydroxide. Compounds 1 and 2 are purified by crystallization. . The purified product will be characterized

Distinguish between operant conditioning‚ observational learning‚ and social learning. How are these different kinds of learning utilized in the work place? Give specific examples for each one. Operant conditioning is a theory that is useful when applied to the workplace in several ways. It addresses how employees interact with one another and with clients to how financially successful a company is annually. Operant learning is positive reinforcement. Another example of operant conditioning would

1.Distinguish between pidgins and creoles. Pidgin language is a simplified language that develops as a means of communication between two or more groups that do not have a language in common. It is most commonly used in situations such as trade‚ or where both groups speak languages different from the language of the country in which they live in (but where there is no common language between the groups). In addition‚ pidgins have a distinct set of characteristics that make them differ from the

Distinguish between Facts and Inferences My wife does it all the time. She will make an assumption based on an inference. Last week‚ we were going to my brother’s house for our annual Christmas party‚ we do that in the month of January‚ and a car happened to pass us in a quick hurry‚ she said to the person driving‚ “do not get mad at me‚ I did not set the speed limit at 55 miles per hour.” I then‚ asked her‚ “how do you know that person is mad at you‚” because she said‚ “he revved
