Identify the reagents necessary to convert benzene into each of the following compounds: 19.29 Identify the product obtained when benzene is treated with each of the following reagents: (a)Fumingsulfuricacid (b) HNO3/H2SO4 (c) Cl2, AlCl3 (d) Ethyl chloride, AlCl3 (e) Br2, Fe ( f ) HNO3 / H2SO4 followed by Zn, HCl (a) Chlorobenzene (c) Bromobenzene (e) Propylbenzene (g) Aniline (aminobenzene) (i) Toluene (b) Nitrobenzene (d) Ethylbenzene (f) Isopropylbenzene (h) Benzoic acid

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.  

i believe the answer is three water molecules
