(a)
Interpretation:
The target molecule transformation should be draw and identified given the starting molecule of
Concept Introduction:
Oxidation Reaction: Generally alcohol can be oxidizing to aldehyde or
Reduction Reaction: This process in which any substance atoms, ion or molecule gains one or more electrons it is called reduction.
(a)

Answer to Problem 15.20UKC
The hydride added to the carbonyl carbon, the polar (C=O) carbon has a partial positive charge, then the reduction process has
Explanation of Solution
Reduction reaction: The given carbonyl molecule is converted into alcohol (b) in this undergoes for reduction process was occurred. The hydride ion added to the carbonyl carbon, because carbonyl carbon is polar it as partial positive charges in carbon atom.
(b)
To determine give the reactions indicate which direction represents reduction and which represents oxidation.
Concept Introduction:
Carbonyl group: This group presence of a
Oxidation Reaction: Generally alcohol can be oxidizing to aldehyde or ketone and aldehyde can be further oxidized to carboxylic acids.
Reduction Reaction: This process in which any substance atoms, ion or molecule gains one or more electrons it is called reduction.
