Explanation:
double bond in chemistry is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In a skeletal formula, a double bond is drawn as two parallel lines (=) between the two connected atoms; typographically, the equals sign is used for this.[1][2] Double bonds were first introduced in chemical notation by Russian chemist Alexander Butlerov.[citation needed]
Double bonds involving carbon are stronger than single bonds and are also shorter. The bond order is two. Double bonds are also electron-rich, which makes them potentially more reactive in the presence of a strong electron acceptor (as in addition reactions of the halogens).
Orchids are now grown through vegetative propagation, rather than seeds, courtesy of developments in cloning. This allows many orchid plants to be grown from a portion of a single orchid plant. This allows even the rare orchid o to be grown in mass. There is also little variation when cloning s done as compared to growing with seeds.
