Fun With Organic And Inorganic

A larger version of the image above can be seen here .

Let $A$ denote the number of oxygen atoms in compound $\ce V$ , $B$ denote the degree of unsaturation of compound $\ce V$ , $C$ denote the degree of unsaturation of compound $\ce {Y18}$ , find $10A+2B+5C$ .

Details and Assumptions :

• The data is sufficient and there exists a unique set of compounds which satisfy this.

• The degree of unsaturation is equal to the number of double bond equivalents (including rings).

• Take major products until and unless specified. Also check the direction of the arrow mark for each reaction.

• There is a compound $\ce { N2}$ in between the reaction, it is not nitrogen gas but its some other compound.

• Start from where its mentioned in the problem, clues are present all over the page and also try and find all the compounds.
