The Lewis structure of C2H4 could be shown below: Formal charge = Valence Electrons – Unbonded Electrons – ½ Bonded Electrons For hydrogen atom: Formal charge=1-0-2/2=0 For Carbon atom: Formal charge=4-0-8/2=0 Since the overall formal charge is zero, the above Lewis ...
Crystallites formed in these gels, which are junction points of the network structure, are spherulitic for iPP gel, plate-like (lamellar) for LHDPE gel, and dendritic or noodle-like (very low-density copolymer with comonomer of I-butene randomly) for LLDPE gel as shown in Figure l(B)....
Using periodic density functional theory calculations, the double bond isomerization of 1-butene to 2-butene over MgO surfaces with and without structure defects is investigated. The basicity of these surfaces was characterized by the adsorption of H 2O and CO 2. The isomerization process involves ...
