Write the molecular formula and structural formula of alkene having five carbon atoms:

Explanation

Solution

Alkenes are a group of hydrocarbons containing at least covalent covalent carbon. It contains one double bond (>C=C<)\left( >C=C< \right) just as the single bonds framed among carbon and carbon (C−C)\left( C-C \right) and carbon and hydrogen (C−H)\left( C-H \right). The C=CC=C double bond is known as the functional group of the homologous series we call alkenes.

Complete step by step solution:
An alkene can just consist of carbon and hydrogen particles. On the off chance that another sort of particle (component) is available in the atom it can't be a hydrocarbon for example alcohols, esters and carboxylic acids contain oxygen particles.
Molecular formula for alkene with 5 carbon atom is C5H10{{C}_{5}}{{H}_{10}} .The molecular formula of a compound might be the empirical formula, or it might be a multiple of the empirical formula.
General molecular formula for alkene: CnH2n{{C}_{n}}{{H}_{2n}}.
Hence, for five carbon the molecular formula of alkene is C5H10{{C}_{5}}{{H}_{10}}
Structural formula for alkene 5 carbon atom is CH2=CH(CH2)2CH3.C{{H}_{2}}=CH\left( C{{H}_{2}} \right)2C{{H}_{3}}. Structural formulas distinguish the location of chemical bonds between the atoms of a molecule. A structural formula comprises symbols for the atoms associated by short lines that represent chemical bonds—one, two, or three lines representing for single, double, or triple bonds, respectively.
The structural formula can also be represented as:
CH3−CH=CH−CH2−CH3C{{H}_{3}}-CH=CH-C{{H}_{2}}-C{{H}_{3}}

Additional Information:
Alkenes find numerous different applications in industry. They are utilized as beginning materials in the amalgamations of alcohols, plastics, lacquers, cleansers, and fills. The main alkenes for the compound business are ethene, propene.

Note:
The longest chain containing the double bond has five carbon atoms, so the compound is a pentene. This compound also belongs to the saturated class. This type of compound is classified as substituted hydrocarbons. And finally the open chain hydrocarbon pentene) is classified as unsaturated hydrocarbon.
