What occurs when an optically active alcohol reacts with HBr to give an alkyl halide? Multiple Choice the chirality center retai
ns its configuration incomplete and varying inversion of configuration takes place at the chirality center complete inversion of configuration takes place at the chirality center the molecule loses its optical activity
The incomplete and varying inversion of configuration takes place at the chirality center.
Explanation:
When optically active alcohols react with HBr an SN1 reaction occurs.
In SN1 reactions an intermediate carbocation is formed in which the nucleophile can attack it on either side of the molecule. Therefore, there is a partial inversion of the center of chilarity of the molecule.
The answer is: Incomplete and varying inversion of configuration takes place at the chirality center.
Explanation:
The bromide ion is characterized by being a weak nucleophile, its high pKb value indicates SN1 and also tends to form a carbocation. The hydroxyl group leaves the bond when it undergoes acidification, leading to the formation of a carbocation. Nucleophilic attack of the bromide ion on the p orbital produces a racemic compound.
One thing incorrect is that when dealing with a compound, such as H2SO4, that has 7 atoms in the chemical formula, the polyatomic ion SO4 doesn’t dissociate into one Sulfur and four Oxygens. SO4 stays and a PAI.
Natural phenomena such as melting glaciers is due to the rise in temperature. This will result to extinction of flora and fauna. Moreover it can cause extreme flooding due to rise in water level in other water bodies such as rivers, lakes
