(a)
Interpretation:
For the given molecule, the IUPAC is to be written.
Concept introduction:
There are two types of acid anhydrides, symmetric and asymmetric. In symmetric acid anhydrides, the alkyl groups bonded to both carbonyl carbons are the same, i.e., formed from dehydration of two molecules of the same
(b)
Interpretation:
For the given molecule, the IUPAC is to be written.
Concept introduction:
Acid anhydrides are of two types symmetric and asymmetric. In symmetric acid anhydrides, the alkyl groups bonded to both carbonyl carbons are the same i.e. formed from dehydration of two molecules of same carboxylic acid. The general form of symmetric acid anhydride name is alkanoic anhydride. In asymmetric acid anhydrides, the alkyl groups bonded to both carbonyl carbons are different i.e. formed from dehydration of two molecules of different carboxylic acids. The general form of asymmetric acid anhydride name is alkanoic anhydride. The two alkanoic groups appear in alphabetical order. The ‘alkanoic’ corresponds to the specific carboxylic acid(s) that undergo(es) dehydration to produce the anhydride. The ‘alkan’ is the root name stands for the longest chain having the carbonyl group.

- Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)arrow_forwardHi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forward
