How would you expect eugenol to react with the following reagents? a. bromine in carbon tetrachloride b. concentrated sulphuric acid at 20 C Alkenes: Alkenes are hydrocarbon chains that contain double bonds between carbon atoms. Alkanes are...
aIn Carl Schmitt’s political philosophy he makes a distinction between the real enemy and the absolute enemy. This latter enemy is the one that negates your own position, questions your very existence. The real enemy denotes our possibility to act, we can react to challenges and threats. The...
How the amines below could be prepared by reductive amination of a ketone or an aldehyde in the presence of an acid. If there is more than one precursor indicate them all. N-Ethylaniline How do you transform an alcohol into an alkene? For example, ...
How do you calculate the pH of a buffer solution when base is added? To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is sub...

Direct alkylation of amines with alkyl halides is a difficult reaction to control. One alternative that works extremely well is to form theimineof an amine with an appropriate aldehyde or ketone, and then to reduce the imine to an amine. This is calledreductive aminationand avoids the problem ...
(or in the ligand). Common positively charged groups include amines and other N-containing groups (lysine, arginine, in proteins), amongst others. Common negatively charged groups include carboxylates and other O-containing groups (glutamate, aspartate...
The capping layer reacts with the excess PbI2 coming from the MAPbI3 layer underneath, forming the RP perovskite phase at the top7. Within 460 min of accelerated aging tests, almost all of the bare MAPbI3 degrades into lead iodide (PbI2), as indicated by the emergent peak at 12.64°...
