Allenes have which general molecular formula
Answers
Answer:
The general formula for the alkenes is C nH 2n, where n is the number of carbon atoms in the molecule. Decene is an alkene. Its molecules contain 10 carbon atoms . ... The formula will be C 10H 20.
Answer:
Explanation:The alkenes comprise a series of compounds that are composed of carbon and hydrogen atoms with at least one double bond in the carbon chain. This group of compounds comprises a homologous series with a general molecular formula of C n H 2 n , where n equals any integer greater than one.
The simplest alkene, ethene, has two carbon atoms and a molecular formula of C 2H 4. The structural formula for ethene is
In longer alkene chains, the additional carbon atoms are attached to each other by single covalent bonds. Each carbon atom is also attached to sufficient hydrogen atoms to produce a total of four single covalent bonds about itself. In chains with four or more carbon atoms, the double bond can be located in different positions, leading to the formation of structural isomers. For example, the alkene of molecular formula C 4H 8 has two isomers.
