4.1: Naming Cycloalkanes - Chemistry LibreTexts
Determine the cycloalkane to use as the parent chain. The parent chain is the one with the highest number of carbon atoms. If there are two cycloalkanes, use the cycloalkane with the higher number of carbons as the parent chain.
19.1 Naming Aldehydes and Ketones - Organic Chemistry
Note in the following examples that the longest chain in 2-ethyl-4-methylpentanal is actually a hexane, but this chain does not include the –CHO group and thus is not the parent. For cyclic aldehydes in which the –CHO group is directly attached to a ring, the ring name followed by carbaldehyde is used.
Nomenclature of Aldehydes & Ketones - Chemistry LibreTexts
2023年1月28日 · As with other ketones the –e ending is replaced with the –one to indicate the presence of a ketone. With cycloalkanes which contain two ketones both carbonyls need to be given a location numbers. Also, an –e is not removed from the end, but the suffix –dione is added.
Nomenclature of Cycloalkanes | MCC Organic Chemistry
If there are two cycloalkanes, use the cycloalkane with the higher number of carbons as the parent chain. If there is an alkyl straight chain that has a greater number of carbons than the cycloalkane, then the alkyl chain must be used as the primary parent chain.

Enthalpies of polar interaction of a series of ketones with methanol (MeOH), dimethylformamide (DMF), benzene. and cyclohexane (c-C6) have been reported (1) using the solvation enthalpy, or AAH(v. --t S), method. This method utilizes en- thalpies of transfer of …
4.1 Naming Cycloalkanes - Organic Chemistry - OpenStax
Because cycloalkanes consist of rings of −CH 2 −units, they have the general formula (CH 2) n, or C n H 2n, and can be represented by polygons in skeletal drawings. Substituted cycloalkanes are named by rules similar to those we saw in ( Section 3.4 ) for open-chain alkanes.
