A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this:
eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol
the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds:
........H..OH...H.............O-H...H...H
........|....|.....|..................|....|.....|
....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H
........|....|.....|..................|....|.....|
....H-O...H....H.................H...H....H
1,2 propan di-ol........1,1 propan di-ol

Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.)
Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O.
Structural formula? Never heard of.
A molecular formula indicates the numbers and kinds of atoms in a molecule. A structural formula indicates the arrangement of the atoms in a molecule. For example, the molecular formula for carbon dioxide is CO2, indicating that each molecule consists of one atom of carbon and two atoms of oxygen. The structural formula for CO2 is O=C=O, which indicates that each oxygen atom is double bonded to the central carbon atom.
There are three types of chemical formulas. Chemical formulas describe chemical reactions. Anyways, the second type of chemical formula is the structural formula. The structural formula is the most informative out of the three, and it is the longest.
A molecular model is a tangible, three dimensional representation of a molecule showing the individual atoms that constitute the molecule, the chemical bonds between the atoms, and the angles between bonds when an atom forms more than one bond. A structural formula is a two dimensional representation of a molecule that contains less complete information than a molecular model but still shows the individual atoms and the bonds between them, sometimes in abbreviated form.
The molecular formula gives the kinds of elements and numbers of atoms of the elements in a molecule of a substance.
A structural formula shows how the atoms of the elements are arranged in the molecule.
For example, the molecular formula for carbon dioxide is CO2. The structural formula is O=C=O .
The chemical formula shows the atoms that make up the molecule, whereas the molecular formula basically states the correct quantity of all the atoms in the molecule.
Explain the similarities and differences in the information shown in a molecular formula and a structural formula for the same substance.
im not sure look up def of each.
Molecules are not the only type of chemicals. There are also elements, ions, radicals, or sections of molecules for which we sometimes want to have formulas also.
Molecular formula is C2H5CH3COO . Structural formula is CH3COOCH2CH3 .
Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
H2O is a molecular formula, since it shows the actual number of each atom in the molecule, and it is also an empirical formula since it shows the atoms in their simplest ratio (2 to 1). In this case the, the molecular formula and the empirical formula are the same.It is not, however, a structural formula, which would show the actual arrangement of the atoms in the molecule. The structural formula for water is HOH which shows the molecule as an H+ radical bonded to an OH- radical.
Yes, structural formulae show how the atoms in a compound are arranged. For example, CH3CH2CH2CH3 is the structural formula for butane. Unlike the displayed formula, it does not show the individual bonds that are formed.
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.
The structural formula show the position of atoms in a molecule.
no
A structural formula represents the molecule graphically, whereas the other does not.
the answer is : A MOLECULAR FORMULA
Nope.... isomers differ only in their structure not in their molecular formula
A molecular formula indicates the numbers of atoms of each element in the molecule, but a structural formula also indicates the arrangement of the atoms in the molecule. For example, H2O is the molecular formula for water, but H-O-H is the structural formula, showing how the hydrogen and oxygen atoms are arranged in the molecule.
