♦ Relevant knowledge
If alcohols are treated with powerful acids to produce alkene, this process is referred to as dehydration of alcohol. When more than one type of alkene is created then the main product is identified through the use of Saytezeff’s law, which says that the primary product is the alkene that is more substituted for a double bond.
The concept used to solve this problem is reagent.
For a chemical reaction to occur, there are some substances that are needed and these are termed as reagents.
Reagents are the substances which are used for the analysis or to bring a desire change in the chemical reaction.
Consider the following reaction:
This is a Jones oxidation reaction. The reagent used is [katex]{\rm{Cr}}{{\rm{O}}_3},{\rm{ }}{{\rm{H}}_{\rm{3}}}{{\rm{O}}^{\rm{ + }}}[/katex]
Consider the following reaction:
This is an oxidation reaction of primary alcohol to an aldehyde. And the reagent used is [katex]{\rm{PCC}}[/katex]
The reaction mechanism is:
Consider the following reaction:
This is a nucleophilic substitution reaction. The reagent used is [katex]{\rm{SOC}}{{\rm{l}}_{\rm{2}}}[/katex]
Consider the following reaction:
It is an SN2 reaction. The reagents used are [katex]{\rm{NaH}}[/katex]
Consider the following reaction:
The reagent used in this reaction is [katex]{\rm{PB}}{{\rm{r}}_{\rm{3}}}[/katex]
Ans:
The reactions of cyclohexyl methanol with the best reagents are shown below:
