Our physical environment is composed of chemicals. Our bodies are composed of chemicals. Understanding the principles of chemistry helps us better understand our world.

It is definitely "an oldie, but goodie" lab! There is nothing new, innovative, or earth-shattering about this lab. The idea has been around for as long as I have, and this is my 28th year in the classroom! My students always love this lab, and they often comment and share their surprise with me over the results they obtain. The most common organic compounds found in living organisms are the proteins, nucleic acids, carbohydrates and lipids. It is very simple in a middle or high school lab to test some foods for the presence of the various organic compounds. How is the student benefited from doing this lab? The lab that I have described here can most certainly be found in any biology lab manual.

Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act.
Alkenyl Functional Group. Carboxylic Acid Derivatives. Carboxylic Acid Derivatives A Substitution Reaction Which Starts With Addition Last time we completed our study of the reactions of aldehydes and ketones, compounds in which a carbonyl group is bonded either to carbons or hydrogens.
The typical reaction pattern for these compounds was addition, with a nucleophile adding to the carbonyl carbon and an electrophile adding to the carbonyl oxygen. Today we'll look at carboxylic acid derivatives. This group of compounds also contains a carbonyl group, but now there is an electronegative atom (oxygen, nitrogen, or a halogen) attached to the carbonyl carbon. This difference in structure leads to a major change in reactivity. Notice that each of these functional groups has either an oxygen, a nitrogen, or a halogen attached to the carbonyl carbon. The typical reactions of these compounds are substitutions -- replacing one of these heteroatoms by a another atom. The first step is familiar from aldehyde and ketone chemistry. WebQuests.

Los alcanos son compuestos formados exclusivamente por carbono e hidrógeno (hidrocarburos), que solo contienen enlaces simples carbono-carbono. Tipos de alcanos Los alcanos se clasifican en lineales, ramificados, cíclicos y policíclicos.
