Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Table of Reagents: Name Chemical formula Melting Point Boiling Point Density Safety Hazards Diethyl ether C4H10O -116.3°C 34.6°C 0.7134 g/ml Flammable Bromobenzene C6H5Br -30.6°C 156°C 1.5 g/ml

Curley’s wife Curley’s wife Only woman in the plot. Wears too much makeup – red fingernails and red shoes with ostrich feathers. Symbolic of women everywhere who are repressed by male centred societies. Utterly alone on the ranch‚ her husband has seen to it that no one will talk to her without fearing a beating from him. Steinbeck’s initial portrayal of her is mean and seductive. Pretty. Young. Flirtatious. Seductive. Others perceive her to be promiscuous

"The Merchant of Venice" is a play that relies on soliloquies to advance the plot‚ create mood and atmosphere‚ and to develop character among all the actors. I am here to prove how this happens in two different soliloquies and show you why Shakespeare put them into the play. My first soliloquy is from Lancelot Gobbo and it is taken from Act 2 Scene 2.I know that Lancelot is a secondary character‚ but this speech is really important in the outcome of this scene. He is talking about if he

The Rivers of France The Rhône system The Rhône is the great river of the southeast. Rising in the Alps‚ it passes through Lake Geneva (French: Lac Léman) to enter France‚ which has 324 miles of its total length of 505 miles. At Lyon it receives its major tributary‚ the Saône. In eastern France the direction of the main rivers is predominantly north-south through the Alpine furrow. The regime of the Rhône is complex. Near Lyon the Rhône and its important Isère and Drôme tributaries‚ draining

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

He is the villain when he sees the opportunity to take revenge on Antonio for the way he has treated him and makes a bond to take a pound of his flesh. His anger is fuelled even more when his daughter runs away and steals his

* Hypotheses: “The velocity and dischage * Increase downstream”. * “Does the river become more efficient downstream and what are the effects on bed load. ” * “The gradient decreases downstream” * The roundness and bed load increase downstream and as the river gets faster it carries greater amounts of bed-load” In my conclusion I will be linking all of these hypotheses to velocity of the river.
