Alcohols can be generated using alkanes, alkyl halides, and carbonyl compounds. Incorporating a Grignard reagent into a carbonyl compound in the presence of ether and ${\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}^{\mathbf{+}}$ creates alcohol.

Alcohol can be transformed into a carboxylic acid, and this reaction constitutes a principal part of organic chemistry. The oxidants employed in this process include Jones reagent, potassium dichromate, etc. A mild oxidizing agent like PCC is used to transform alcohols into aldehydes.

a. The structure of compound A can be given as:

Structure of compound A

Axial hydrogens are oxidized faster than equatorial hydrogens. The three-dimensional structure of compound A can be given as:

Three-dimensional structure of compound A

Hence, the OH group present at the axial part is oxidized faster than the one present at the equatorial region.

b. The structure of compound B can be given as:

Structure of compound B

Axial hydrogens are oxidized more quickly than equatorial hydrogens. The OH group in compound B that gets oxidized faster is found at the axial position. The three-dimensional structure can be given as:
