The key difference between Caro’s acid and Marshall’s acid is that Caro’s acid contains one sulfate group, whereas Marshall’s acid contains two sulfate groups. Caro’s acid and Marshall’s acid are inorganic acid compounds containing sulfate groups. They are named as peroxymonosulfuric acid and peroxydisulfuric acid, respectively. As these names imply, these inorganic compounds contain peroxide […]
Difference Between Polycyclic and Polynuclear Aromatic Hydrocarbons
The key difference between polycyclic and polynuclear aromatic hydrocarbons is that the term polycyclic aromatic hydrocarbon describes the presence of two or more cyclic structures fused to each other whereas the term polynuclear aromatic hydrocarbon describes the presence of more than one atom. The terms polycyclic aromatic hydrocarbons and polynuclear aromatic hydrocarbons refer to the […]
Difference Between MnO2 and CuO
The key difference between MnO2 and CuO is that MnO2 is the oxide of manganese, whereas CuO is the oxide of copper. MnO2 and CuO are inorganic compounds which have a similar appearance, existing as blackish-brown solids at room temperature. Therefore, it is very difficult to distinguish these two solid compounds just by looking at […]
Difference Between Oxidation Potential and Reduction Potential
The key difference between oxidation potential and reduction potential is that oxidation potential indicates the tendency of a chemical element to be oxidized. In contrast, reduction potential indicates the tendency of a chemical element to be reduced. Oxidation potential and reduction potential are two types of electrode potential values for chemical species given in Volts […]
Difference Between Classical and Nonclassical Carbocation
The key difference between classical and nonclassical carbocation is that classical carbocations have a carbon atom having six electrons in three chemical bonds, whereas nonclassical carbocations have a three-center two-electron structure. A carbocation is a chemical species that is a moiety of an organic molecule. It has a positive charge on a carbon atom. A […]
Difference Between Beryllium and Magnesium
The key difference between beryllium and magnesium is that beryllium atom has two energy levels containing its electrons, whereas magnesium atom has three energy levels containing its electrons. Beryllium and magnesium are two adjacent alkaline earth metals. That means; both these chemical elements are in the same group (group 2), but in different periods, i.e., […]
Difference Between Potash and Polyhalite
The key difference between potash and polyhalite is that the term potash refers to the mineral salts containing potassium, whereas the term polyhalite refers to the hydrated sulfate mineral having potassium, calcium and magnesium ions. Potash and polyhalite are mineral compounds we can find in nature. Both these are water-soluble minerals and are very useful […]
Difference Between Porphyrin and Protoporphyrin
The key difference between porphyrin and protoporphyrin is that porphyrin is a group of aromatic chemicals which has four modified pyrrole subunits interconnected to each other, whereas protoporphyrin is a derivative of porphyrin which has propionic acid groups. Both porphyrin and protoporphyrin are deeply coloured chemical species. These are macrocyclic organic compounds which contain several […]
Difference Between Inner Sphere and Outer Sphere Mechanism
The key difference between inner sphere and outer sphere mechanism is that inner sphere mechanism occurs between complexes via a binding ligand whereas outer sphere mechanism occurs between complexes that do not undergo substitution. Inner sphere mechanism and outer sphere mechanism are two different types of electron transfer in coordination complexes. The inner sphere mechanism […]
Difference Between Back Bonding and Coordinate Bonding
The key difference between back bonding and coordinate bonding is that back bonding refers to a chemical bond that forms between an atomic orbital of one atom and an antibonding orbital of a ligand whereas coordinate bonding refers to the sharing of a pair of electrons between an electronegative species and an electro-deficient species. Coordinate […]
