... Here the carboxylation is carried out by using large excess of CO2 and the acid is the primary product. In the case of primary and secondary amides the principal role of the Grignard reaction is to remove the acidic protons the the nitrogen (as in the case of the acid above). However, if using tert ...

Haloalkanes
... The nucleophile OH- approaches the carbon atom attached to Br on the opposite side of the molecule in order to minimize repulsion between RX and OH-. A bond begins to form between O and C whereas the C—Br bond weakens, and a transition state is reached in which C is partially bonded to both O and Br ...

... Because its 600 bond angles allow poor orbital overlap, its bonds are weak. As a result, it is thermally unstable and rearranges to propene at 10000C via a first-order reaction: • The rate constant is 9.2s-1; (a) What is the half-life of the reaction? (b) How long does it take for the concentration ...
