What has greater priority?alkenes or alkynes?what we learnt was that alkenes have greater priority.Usually if some group has greater priority that will be the suffix..but when it comes to alkenes and alkynes..the -yne part comes last.it So let’s talk about the nomenclature of alkynes now.
Alkenes are hydrocarbons that contain one or more double bonds, while alkynes contain one or more triple bonds. The naming conventions for these compounds are Alkene and alkyne compounds are named by identifying the longest carbon chain that contains both carbons of the double or triple bond. The foundation of organic nomenclature requires an ability to name alkanes, alkenes and alkynes. There are only minor differences in the nomenclature of cycloalkanes and acylic alkanes. Often a ring can be drawn in more than one way.
Alkanes, alkenes, and alkynes are similar in name but they are slightly different. Eventhough the use of them may overlaps in some cases, each of Even though they come from the same hydrocarbon compound, the different bond leads to different use in industry. There are several uses of alkanes
Alkynes: Nomenclature. Although many different types of nomenclature, or naming systems, were employed in the past, today only the International Union of Pure and Applied Chemistry (IUPAC) nomenclature is acceptable for all scientific publications.

Naming alkynes follows the same rules we discussed earlier for the IUPAC nomenclature rules for alkanes. This is the brief summary of steps If both directions for numbering the parent chain give the same number, the alkene gets a priority, so you need to number the chain in the direction that gives
Naming alkynes is just like naming alkanes To start, replace the ending “ane” with “yne” Triple bonds get the lowest possible number on the parent carbon chain5, therefore pent Carbon alkyne starts on? it is closer to the end of the longest chain than the double bond Carbon alkene starts on?
Alkenes: Nomenclature. An alkene is a hydrocarbon characterized by a double bond between two constituent carbon atoms. Note that alkenes are named by replacing the -ane ending of an alkane with -ene. The position of the double bond is not ambiguous in the case of ethene (commonly called

Alkenes and alkynes are named with the same prefixes as their alkane counterparts but their suffixes are changed to -ene and – yne, respectively. The position of the double or triple bond within the carbon chain is denoted by the position of the carbon within the bonded pair that has the lower numbering.

Alkynes are similar to alkenes in both physical and chemical properties. For example, alkynes undergo many of the typical addition reactions of In comparison to alkanes, alkenes and alkynes are much more reactive. In fact, alkenes serve as the starting point for the synthesis of many drugs
