Investigatory Project In Chemistry (Rose Petal Perfume) Prepared by : Jhannine Mae Talain Eileen Shelly Velasquez III-St.Isidore January 13‚2012 Prepared for : Mrs. Geraldine M. Yadao I-Introduction We thought and brainstormed about what we are going to do for our investigatory project. One of us gave the idea to concentrate on a particular topic‚ which is about soap making but after all the long thinking and brainstorming‚ we decided to come up with a perfume as a product with the use of rose

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf.

Introduction The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1)‚ this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates‚ in a single step‚ which explains the stereospecificity due to substituents not being given the chance to “switch around”. (1)These six membered rings are synthesized by reacting a dienophile

chain‚ meaning normal (n-alkanes) are called: methane‚ ethane‚ propane‚ butane. The superior alkanes names are compound with a numeric prefix (which shows the number of carbon atoms present in the molecule) and the ending “-ane”. For example: pentane‚ hexane‚ heptane‚ and octane. For the hydrocarbons with two groups of methyl (-CH3) at the end of a linear chain‚ you use the prefix “iso-” at the name of the hydrocarbon‚ and for those containing three -CH3 groups at the end of the chain‚ you use the prefix
