1. a common way to understand if a mechanism is correct is to use deuterium (d = 2h) in place of hydrogen in a reaction (the method is called isotopic labeling). if dcl in d2o replaced hcl and d2so4 replaced h2so4 and so on for all solvents in this reaction, for which mechanisms would would expect deuterium to be present in the double bond of fumaric acid? explain how your arrived at your prediction using the mechanisms provided.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

c. is the answer
