Show how 2-butanol can be made from 2 molecules of acetylene and any necessary inorganic reagents. In class we’ve only learned how to use NaNH2 in order to put two smaller reactions together.
I know how to use NaNH2 in a 2 combine two reactions involving an alkyne and then an alkyl halide but I’m [...]
In chem lab, we did an oxygen generation experiment using hydrogen peroxide as the reactant and manganese dioxide as the catalyst. After the generation of the gas, we performed various experiments with the bottles of oxygen, such as the wood splint test, etc. I now have to write word equations for the following:
- Combustion of [...]
This is urgent!
My chem teacher is making us test a slogan to see if it is a valid slogan.
Any ideas?
