Predict the product(s) that would result when molecules (a)–(p) are allowed to react under the following conditions: (xi) HOCl, H₂O (xii) HIO₄. If no reaction occurs, write 'no reaction.'  
(a)

Identify the alcohols that would undergo oxidation to produce the following carbonyl compounds.

(a)

Fill in the missing reactant, reagent, or product for each of the following oxidation reactions.

(a)

Unfortunately, the use of NMO creates an additional green chemistry problem. What is the problem and how might it be solved?

Predict the product(s) that would result when molecules (a)–(p) are allowed to react under the following conditions: (ix) PCC; (x) H₂CrO₄ , H₂O. If no reaction occurs, write 'no reaction.'  

(a)

We explain in Chapter 24 that bisphenols can be oxidized to quinones.

(a) Calculate the oxidation numbers of C1 and C₂ in going from reactant to product.

(b) Provide a mechanism for this transformation. [The reaction begins like the alcohol oxidations of Section 13.9.]

In Assessment 13.48, identify the individual step that represents the general mechanism for all alcohol oxidation reactions.

Predict the product(s) that would result when molecules (a)–(p) are allowed to react under the following conditions: (i) SOCl₂ ; (ii) PBr₃ ; (iii) SOCl₂ , NEt₃ (iv) 1. TsCl, Et₃N 2. NaCN; (v) 1. TsCl, Et₃N 2. NaOt-Bu (vi) H₂SO₄ (vii) HCl; (viii) HBr; (ix) PCC; (x) H₂CrO₄ , H₂O (xi) HOCl, H₂O (xii) HIO₄ If no reaction occurs, write 'no reaction.'

(c)

In light of Figure 24.22, provide a mechanism by which para-dihydroxybenzene is oxidized to para-quinone.
