Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

This reaction will most likely follow an S_N2 mechanism with the alkoxide displacing the bromine in a concerted transition state. There is no stereocenter involved here, but if there was, inversion of configuration would be observed.

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

In the presence of excess alkyl halide, ammonia will undergo exhaustive alkylation to form the quaternary ammonium salt by a series of S_N2 reactions. The product here is tetraethylammonium bromide although you need not write the anion in the drawing pallet (but you should on the exam!).

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

You should assume that this reaction will follow an S_N2 mechanism with the iodide anion displacing the toluenesulfonate in a concerted transition state. There is no stereochemistry shown here, but if there was, inversion of configuration would be observed. If an S_N1 mechanism was involved, the product would be the rearranged 1-iodo-1-methylcyclohexane.

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

This reaction will most likely follow an S_N2 mechanism with the thiolate displacing the chlorine in a concerted transition state. There is no stereocenter involved here, but if there was, inversion of configuration would be observed.

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

This reaction will most likely follow an S_N2 mechanism with the amine displacing the bromine in a concerted transition state. There is no stereochemistry shown here, but if there was, inversion of configuration would be observed. On the drawing pallet, draw the product as the neutral amine.

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

This reaction will most likely follow an S_N1 mechanism with the intermediate formation of the tert-butyl cation, followed by attack of the amine. There is no stereochemistry involved here, but if there was, racemization of configuration would be observed. On the drawing pallet, draw the product as the neutral amine.

Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

This reaction will most likely follow an S_N2 mechanism with the amine displacing the bromine in a concerted transition state. There is no stereochemistry involved here, but if there was, inversion of configuration would be observed. On the drawing pallet, draw the product as the neutral amine.

That is correct!

Sorry, that is not correct. You should modify your structures and try again. If cis-trans- stereochemistry is required, please make sure you have drawn the appropriate isomer using the "wedge bonds".
