WebJan 23, 2024 · Ethene, Propene, and Butene exists as colorless gases. Members of the 5 or more carbons such as Pentene, Hexene, and Heptene are liquid, and members of the 15 carbons or more are solids. Density Alkenes are lighter than water and are insoluble in water due to their non-polar characteristics. Alkenes are only soluble in nonpolar solvents. … WebIf they donate some electron density to the carbocation, this reduces its positive charge and lowers the energy (stabilizes) the cation. A 1,1-dimethylethyl cation (3°), for example, has three methyl groups attached to the cationic carbon. An ethyl cation (1°) has only one methyl group on the cationic carbon. So 3° is more stable than 1°. 1 comment
