The Wittig reaction is a unique reaction that can be carried out in various ways as our prompt exemplifies. We will be primary focusing on the second of the three schemes. In The usual formation of an ylide occurs via Sn2 attack of a PR3 group on an alkyl halide‚ which is then followed by a strong base deprotonating of one of the hydrogens on the methyl which the PR3 attacked. Before we dive into the details of the reaction occurring in scheme 2 it will be important to understand the mechanism which

Observing the and determining the reaction rate of photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is

of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This
