The key difference between African and South American Cichlids is that the African cichlids live in freshwaters originating from three great lakes of Africa while South American cichlids live in the freshwaters of South and Central America including the Arizona river. Moreover, looking at their behavior, the African Cichlids are aggressive and prefer to live […]

Difference Between EDG and EWG
The key difference between EDG and EWG is that the EDG (stands for Electron Donating Groups) can increase the electron density of a conjugated pi system whereas the EWG (stands for Electron Withdrawing Groups) decreases the electron density of a conjugated pi system. EDG and EWG are electrophilic aromatic directing groups. Both of these are […]
Difference Between Chemical and Organic Evolution
The key difference between chemical and organic evolution is that the chemical evolution occurs due to changes in the structure of the molecules; from complex molecules to simple molecules with the passage of time whereas the organic evolution occurs due to the changes in the genetic composition of populations of organisms in response to environmental […]
Difference Between HOMO and LUMO
The key difference between Homo and Lumo is that the HOMO donates electrons whereas the LUMO receives electrons. The terms HOMO and LUMO are under the subtopic “molecular orbital theory” in general chemistry. The term HOMO stands for “highest occupied molecular orbital” while the term LUMO stands for “lowest unoccupied molecular orbital”. We call them […]
Difference Between Energy and Exergy
The key difference between energy and exergy is that the energy is a quantitative measurement whereas the exergy is a qualitative measurement. Energy is the ability of a substance to perform work. It is hence a quantitative parameter. But exergy gives the maximum work that a substance can perform. Therefore, it is a qualitative parameter. […]
Difference Between Endo and Exo Diels Alder
The key difference between Endo and Exo Diels Alder compounds is that the Endo Diels Alder product has its substituents on the same face of the bridged ring system whereas the Exo Diels Alder product has its substituents on the opposite faces of the bridged ring system. Endo-Exo isomerism is a special type of isomerism […]
Difference Between Node and Internode
The key difference between node and internode is that the node is the point on a stem where a leaf or a bud or a branching twig originates while internode is the distance or the area between two adjacent nodes. Plant stem is one of the main parts of a plant. In the plant stem, […]
Difference Between Ionic and Nonionic Surfactants
The key difference between ionic and nonionic surfactants is that the ionic surfactants contain elemental cations or anions present in its formulation whereas the nonionic surfactants have no cations or anions present in its formulation. Surfactants are surface active agents. That means, these compounds can reduce the surface tension between two substances; two liquids, a […]
Difference Between Biogas and Natural Gas
The key difference between biogas and natural gas is that the biogas is a renewable source of energy whereas the natural gas is a non-renewable source of energy. Biogas is a naturally occurring gas that forms from the breakdown of organic matter in the presence of anaerobic bacteria while natural gas is a naturally occurring […]
Difference Between Water Gas and Producer Gas
The key difference between water gas and producer gas is that the water gas contains flammable gases whereas the producer gas contains both flammable and non-flammable gases. Both water gas and producer gas are mixtures of several gases. Water gas contains carbon monoxide and hydrogen gases. Producer gas contains carbon monoxide and hydrogen gases along […]
