Explanation:
Electronegativity is the ability of an electron to attract electrons.
Now, due to the fact that halogens need just one more electron to become stable in their outermost shell, it means all halogens are electronegative.
However, the smaller the atomic number, the bigger the charge density and thus the more electronegative.
Thus, it is the halogen element with the highest atomic number further down the periodic table that will have the least electro negativity and thus require highest amount of energy to attract other electrons.
Thus, since chlorine (Cl) has the least atomic number of 17, then it means that it will be the one that will easily accept the electrons the most from other elements. Therefore the process of transferring electrons from potassium to chlorine will take the least amount of energy.
According to picture below, answer is d.c4h2n2o4 and c2hno2.
Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this case C₄H₂N₂O₄). Molecular formula shows that compound has four carbon, two hydrogen, two nitrogen and four oxygen atoms.
Empirical formula gives the proportions of the elements present in a compund but not the actual numbers or arrangement of atoms. C : H : N : O = 2 : 1 : 1 :2.
