Web23. jan 2024 · Step 2: Chain Propagation. In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a π bond. Web4 Styrene, or ethenylbenzene or phenylethene, may contain the inhibitor 4-(dimethylethyl)-benzene-1,2-diol (4-tert-butyl catechol) which needs to be removed by washing with 1 mol L-1 NaOH(aq) then with water in a separating funnel. Dry the phenylethene over anhydrous sodium sulfate, Na 2 SO 4 (s), for 10 minutes. 十三 マンハッタン
