WebPoly (ethene) is a polymer made from a very large number of ethene molecules combined together. The C=C double bond in ethene is involved in the polymerisation reaction. It … WebThe simplest alkenes, with only one double bond and no other functional groups, form a homologous series of hydrocarbons with the general formula CnH2n. ... This chapter focuses on polymers made from monomers that contain a carbon–carbon double bond through which the polymer is made by addition polymerization as discussed in Section …
WebThe alkenes have a carbon-carbon double bond, this means that they have one σ (sigma) bond, and also one pi bond which occurs when there is a side by side overlap of p orbitals. What is the shape of a alkene and the bond angle? Spatial arrangement around the C=C is trigonal planar with the bond angle 120°. Draw propene. Draw hexene. Draw pentene.
