PPT-Naming the Alkenes

111 Alkenes are characterized by the presence of a double bond The general formula of an alkene is C n H 2n the same as for a cycloalkane Common nomenclature for alkenes replaces the corresponding alkane suffix ane with ylene . 6 286 Relative Stability of Alkenes Based On Molar Heats of Hydrogenation H hyd 276 kcalmol H hyd 286 kcalmol Trans cis brPage 3br Relative Stability of Alkenes Based On Molar Heats of Hydrogenation 327 kcalmol 297 kcalmol 280 kcalmol 286 kcalmol Day 2.

To get the answer, first write the valences:. 1 Chemical Tests for Alkanes, Alkenes, and Aromatic Compounds Introduction There are four types of hydrocarbons : alkanes, alkenes, alkynes, and aromatic compounds, each type with different chemical Objectives.

Alkanes, alkenes, alkynes and aromatics. Types of Hydrocarbons. Hydrocarbons contain C and H. There are 4 families, alk. anes. only have C-C single bonds, alk. enes. have at least one C=C and alk. ynes. Ch. . 16. Covalent Compounds.
