Explanation:
Write the IUPAC name of CH3 - CH2 - CH2 - CH=CH2.
Answer:
A single chemical compound can have several acceptable systematic names and the systematic method of naming organic chemical compounds is called IUPAC Nomenclature but no two compounds can have the same.
Rules underlying IUPAC nomenclature of alkanes, alkenes, and alkynes are discussed below
The longest hydrocarbon chain is selected and is termed as parent chain in case of alkanes.
For alkanes suffix ‘-ane’ is used, for alkenes, suffix ‘-ene’ is used and suffix ‘yne’ is used for alkynes.
The parent chain is numbered such that we reach to the double-bonded or triple bonded carbon atom earliest. The position of the carbon atom with the double bond is mentioned in numerals.
In the case of multiple double bonds in the carbon chain, Greek numerical prefixes such as di, tri are used to denote their number.
Given chemical compound CH3 – CH2 – CH2 – CH=CH2
Longest chain has 5 carbon atoms.
It is an alkene so suffix used is ‘ene’.
A double bond is at 1-C position.
The IUPAC name of CH3 – CH2 – CH2 – CH=CH2 is Pent-1-ene.
