Grignard synthesis triphenylmethanol
The mechanism is shown in the figure 4 as below.
After that, the temperature continues to fall until the last second the time was recorded. In this reaction, the bromide ions are escaped from the alkyl bromide and combine with the sodium ions to form sodium bromide to achieve stable molecule.
The synthesis triphenylmethanol is shown in the figure 1 as below. The mixture is shaked and the lower layer is removed.
The washing is repeated for two times with 20cm3 of water. The displacement of a hydroxyl group by halide ion is successful only in the presence of a strong acid.
However, the graph for the solution of naphthalene and substance X exhibits a staircase-like shape. The first part involves the formation of n-butyl bromide thesis of the pianist 1-butanol.
The acid also protonates the water as it is produced in the reaction and deacticvates it water as a nucleophile, hence the water keeps the butyl bromide from being converted back into the alcohol by nucleophilic attack of water. As a result, an ether with butyl ethyl groups is formed which is known as n-butyl ethyl ether. When the graph of the time versus temperature was plotted, a longest horizontal portion which is the constant temperature of the graph indicates the freezing of the pure liquid.
The essential feature of the SN2 mechanism is that take place in a single step without intermediates when the incoming nucleophile, hydrogen bromide reacts with the 1-butanol from a direction opposite the group that leaves. The water is formed after the bromide successfully becomes part of the molecule.
However, dibutyl ether also can be formed due to the strong sulphuric acid used.
