(a)
Interpretation:
The formation of secondary alcohol using a two-carbon compound is to be determined.
Concept Introduction:
Secondary alcohol can be generated in many ways, one of the possible ways being the addition of a Grignard reagent with a two-carbon
(b)
Interpretation:
A plausible reaction for the formation of the secondary alcohol product has to be determined using a two-carbon starting material.
Concept Introduction:
Secondary alcohol can be generated in many ways, one of the possible ways being the addition of a Grignard reagent with a two-carbon aldehyde, followed by hydrolysis of the intermediate molecule. Using acetaldehyde as the starting material, the product can be obtained.
(c)
Interpretation:
The formation of four-carbon primary alcohol using a two-carbon compound is to be determined.
Concept Introduction:
Primary alcohol can be generated in many ways, one of the possible ways is a substitution reaction of an
(d)
Interpretation:
A plausible reaction for the formation of the secondary alcohol product has to be determined using a two-carbon starting material.
Concept Introduction:
Secondary alcohol can be generated in many ways. One of the possible ways is the addition of a Grignard reagent with a four-carbon aldehyde, (which can be formed from a two-carbon compound by the addition of alkynide) followed by hydrolysis of the intermediate molecule. Using bromoethane as the starting material, the product can be obtained.
