C6h5co2ch2c6h5 can be synthesized by an sn2 reaction. draw the structures of the alkyl chloride and nucleophile that will give this compound in highest yield. use the wedge/hash bond tools to indicate stereochemistry where it exists. include all valence lone pairs in your answer. separate multiple reactants using the + sign from the drop-down menu. when a metal counterion is needed, use na+, but draw it in its own sketcher.

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.
