WebThere are also some compounds, for example hydrazine N 2 H 4, where molecules contain a bond between two atoms of the same element. Carbon has an unusual ability to bond to itself. Carbon atoms can join together to make molecules with very long chains of carbon atoms, and there are also compounds where carbon forms rings.

Organic Chemistry Alkanes
WebIsomers. Isomers are compounds with the same molecular formulae but different structural formulae. They have the same number of each type of atom. They can be part of the same or different homologous series, e.g. alkenes and cycloalkanes can be isomers. Due to their different structures their physical properties (melting point, boiling point ... WebA homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. Those with only carbon-carbon single bonds are saturated. If a compound... WebRecap - Cycloalkanes. The third homologous series is the cycloalkanes. Their names all end in –ane and begin with cyclo-, for example cyclopropane. The cycloalkanes have the general formula \ ( {C_n} {H_ {2n}}\). Even though they have the same general formula as the alkenes, the cycloalkanes are saturated and contain only single bonds. harvard pilgrim health care covid test
