(c)
Interpretation:
The reaction should be completed.
Concept Introduction:
Dehydration reaction:
Removal of water molecule from the reaction when the alcohol is treated with strong acid like sulfuric acid.
Alcohol is reaction with concentrated sulfuric acid, first alcohol gets protonated forms carbocation (more stable carbocation) followed by elimination of proton (
Tertiary carbocation is more stable than the secondary, secondary carbocation is more stable than primary.
In Dehydration reaction, sulfuric acid is act as a proton donor, and which is used to protonate the alcohol and makes carbocation therefore sulfuric acid is the driving force of the reaction. Dehydration reaction will not go without acid (sulfuric acid).
(d)
Interpretation:
The reaction should be completed.
Concept Introduction:
Bromination of alkenes:
Alkene undergoes bromination which yields the dibromo compound (vicinal dibromides or 1,2-dibromides).
(e)
Interpretation:
The reaction should be completed.
Concept introduction:
Thiols:
The general structure of thiol is
Oxidation of thiols:
Thiol undergoes oxidation using
(f)
Interpretation:
The reaction should be completed.
Concept introduction:
Hydration:
When alkene is undergoes hydration with water in the presence of sulfuric acid which yields the alcohol. In this reaction, the water molecule will behave like a hydrogen halide to the alkene which gives the addition product this reaction is known as a hydration reaction.
Alkene is reaction with water in the presence of sulfuric acid, first step is proton (
In hydration reaction, sulfuric acid is act as a proton donor, which is the driving force of the reaction. Hydration reaction will not go without acid (sulfuric acid).
