Experiment 6 titled “Organic Chemistry” and the purpose of this lab is to get familiar with some organic functional group and test certain reactions of selected functional groups. To do the first part of the experiment (combustion test)‚ instructor demonstration in hood‚ and record the observation. Part A (combustion of toluene) pour 1 milliliter of toluene into a evaporating dish and ignite it with a flaming wood splint. Most importantly put the flame with a watchglass. Part B (combustion of ethyl

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

Analytical chemistry Analytical chemistry is the branch of chemistry that deals with the separation‚ identification and determination of components in a sample. Analytical chemistry can be divided into two branches‚ qualitative and quantitative. Qualitative analysis It deals with the identity of the constituents that are in an analytical sample. Quantitative analysis It deals with the determination of how much of a given substance is in the sample. The quantitative analyses are classified
