7.4: Naming Alkenes - Chemistry LibreTexts
2024年10月12日 · Alkenes contain carbon-carbon double bonds and are unsaturated hydrocarbons with the molecular formula is C n H 2n; this is also the same molecular formula as cycloalkanes. The parent chain of an alkene is the longest chain containing both carbon atoms of the double bond. Alkenes are named by dropping the-ane ending of the parent and adding ...
Nomenclature of Alkenes - Chemistry LibreTexts
2023年1月23日 · Alkenes are named using the same general naming rules for alkanes, except that the suffix is now -ene. Here is a chart containing the systemic name for the first twenty straight chain alkenes. Name
7.3 Naming Alkenes - Organic Chemistry - OpenStax
Alkenes are named using a series of rules similar to those for alkanes (Section 3.4), with the suffix -ene used instead of -ane to identify the functional group. There are three steps to this process. STEP 1 Name the parent hydrocarbon. Find the longest carbon chain containing the double bond, and name the compound accordingly, using the suffix ...
13.1: Alkenes- Structures and Names - Chemistry LibreTexts
2024年4月28日 · Although there is only one alkene with the formula C 2 H 4 (ethene) and only one with the formula C 3 H 6 (propene), there are several alkenes with the formula C 4 H 8. Here are some basic rules for naming alkenes from the International Union of Pure and Applied Chemistry (IUPAC):
Naming Alkenes Suffix: -ene Many of the same rules for alkanes apply to alkenes 1. Name the parent hydrocarbon by locating the longest carbon chain that contains the double bond and name it according to the number of carbons with the suffix -ene. H 3 C CH 2 CH 2 C CH 2 H 3 C CH 2 H 3 C CH 2 CH 2 C CH 2 H 3 C CH 2 Parent = pentene not hexene ...

Understanding Alkenes. Alkenes are hydrocarbons that contain a carbon-carbon double bond, represented by C=C. This double bond is a defining feature of alkenes and plays a crucial role in their reactivity and properties. Step-by-Step Guide to …
E and Z Notation For Alkenes (+ Cis/Trans)
2016年11月3日 · The E/Z system is comprehensive for all alkenes capable of geometric isomerism, including the cis/trans alkene examples above. We often use cis/trans for convenience, but E/Z is the “official”, IUPAC approved way to name alkene stereoisomers].

Here are some basic rules for naming alkenes from the International Union of Pure and Applied Chemistry (IUPAC): The longest chain of carbon atoms containing the double bond is considered the parent chain. It is named using the same stem as the alkane having the same number of carbon atoms but ends in –ene to identify it
