Question

Which alcohol reacts faster with $HCl$ and $ZnC{l_2}$?

Answer 1

We have to know that in organic chemistry stability of molecules and ions are very important. Carbon ions are classified as two types. There is carbocation and carbanion. The carbon atom which has a positive charge is called carbocation. The carbon atom which has a negative charge is called carbocation.

Complete answer:
The chemical formula of zinc chloride is $ZnC{l_2}$.
The chemical formula of hydrochloric acid is $HCl$.
Tertiary alcohol reacts faster with hydrochloric acid with zinc chloride compared with secondary and primary alcohol. This reactivity is due to the carbocation stability. Secondary alcohol reacts faster with hydrochloric acid with zinc chloride compared with primary alcohol. This reactivity is also due to the carbocation stability. Because Tertiary carbocation is more stable than secondary and primary carbocation. Secondary carbocation is more stable than primary carbocation.
Due to this kind of nature primary alcohol is not able to react faster with hydrochloric acid with zinc chloride.
Compared to tertiary alcohol, 2-methyl propan-2-ol reacts faster with hydrochloric acid with zinc chloride due to similarity of methyl group in the structure.
According to the above discussion, we conclude 2-methyl propan-2-ol as the tertiary alcohol reacts faster with hydrochloric acid with zinc chloride.

Note:
We need to know that in organic chemistry oxidation and reduction are important concepts. The oxidation and reduction are used to convert one functional group of molecules to another functional group. One homologous form to another homologous form of hydrocarbon is also possible in oxidation and reduction reaction. In one reaction oxidation followed by reduction reaction or the reduction reaction followed by oxidation reaction is called redox reaction. The oxidation reaction means the addition of oxygen or the removal of hydrogen or the loss of electrons in the reaction from reactant to product. The reduction reaction means the addition of hydrogen or the removal of oxygen or gain of electrons in the reaction from reactant to product.
