Draw ten skeletal representations constitutional isomers missing from column 2 in Model 1 as you can. (Hint: Other than cyclohexane‚ there are 11 ways to draw a six-carbon backbone that contains a ring. Plus there are isomers of cyclohexane that do not contain a ring.) (10 points) 3. Are

Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double

Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325

Lab #2 (Part A‚B) Due date: Oct 5‚ 2010 1 - Theory and mechanism Epoxidation is a reaction of an alkene with a peroxycarboxylic acid (also called peracid) to produce an epoxide product‚ generally performed in inert solvents‚ such as dichloromethane. The epoxide product is a cyclic ether in which the ring contains three atoms. The alkene gains an oxygen from the peracid in a syn fashion. In this experiment‚ R-(－)-carvone is reacting with MCPBA‚ a peracid‚ to produce the epoxide product.
