Examples of solvent attack
WebExamples of polar aprotic solvents are acetone, dimethyl formamide (DMF), and dimethylsulfoxide (DMSO): each is polar, but lacks a potentially acidic proton such as the H that is bonded to the O in ethanol CH 3 CH 2 OH or in water H-O-H. Water (and methanol and ethanol) is a polar protic solvent. In a polar aprotic solvent, the negative end of ...

Solvents in Aerosols is tango ballroom or latinFour factors affect the rate of the reaction: The substrate plays the most important part in determining the rate of the reaction. This is because the nucleophile attacks from the back of the substrate, thus breaking the carbon-leaving group bond and forming the carbon-nucleophile bond. Therefore, to maximise the rate of the SN2 reaction, the back of the substrate must be as unhindered as possible. Overall, this means that … is tango card legitWebExample: Consider a reaction of methyl bromide with sodium hydroxide, gives sodium bromide as a side product with methanol as the main product. ...
