C2 or KOH. 6 mm Hg at 25 °C indicates 1,1-dibromoethane will exist solely as a vapor in the atmosphere. Halogenation of Alkenes – Organic Chemistry Reaction Mechanism November 18, 2013 By Leah4sci 5 Comments Reaction Overview: The alkene halogenation reaction, specifically bromination or chlorination, is one in which a dihalide such as Cl2 or Br2 is added to a molecule after breaking the carbon to carbon double bond. It has practically no flammability at lower temperatures. แอลเคน จะไม่ทำปฏิกิริยาฟอกจางสีของ Br2/CCl4 ได้ต่อเมื่อ (C2H4 และ. Molecular polarity depends on both individual bond polarities and molecular geometry, the latter of which we can predict using VSEPR theory. - con Br2 en CCl4 da adición electrofílica (AE): CH2=CH2 + Br2/CCl4 → CH2Br-CH2Br.
