Solved: Determine the number of protons and the number of

Solution : First let’s see what is molecular formula and structural formula and then we will write the formulas for the given compounds. Step 1 : Molecular formula is a chemical formula that gives the total number of atoms of each element in each molecule of a substance For Example : C H2s6he molecular formula of ethane. 1 molecule of ethane contains 2 atoms of Carbon and 6 hydrogen (H) atoms. Structural formula represents the order in which the atoms in a molecule are connected that is it shows the arrangement within the molecule of a toms a nd bonds. It is a graphic structure showing the ar rangement of atoms. For Example : The structural formula for ethane (C 26 is : The black colored atom is Carbon(C), red colored atom is Oxygen(O) and white colored atom is Hydrogen(H), others are mentioned in the compounds given.
