  1. Pembentukan vinilidin dan vinilin berdasarkan reaktivitas selektif Si(100)2x1 arah isomer iso, cis, dan trans dari dikloroetilen Oleh : Silvana Dwi Nurherdiana 1415201011 Dosen : Prof. Dr. rer. nat. Irmina Kris Murwani 1

  2. PENDAHULUAN Cis-dikloroetilen +0,20 a.u. Trans-dikloroetilen +0,25 a.u. Iso-dikloroetilen -0,35 a.u. +0,76 a.u. Si(100)2x1 Mekanisme adsorpsi sikloadisi Vinilidin Vinilin 2

  3. MEKANISME REAKSI SIKLOADISI 1. Kemungkinan keadaan intermediet Kuat ikatan : Si-H 71 kkal/mol C-H 81 kkal/mol Struktur 2 Interaksi ikatan mono-s Struktur 1 Kompleks-p tri-atomik Nagao, dkk, 2004 Diradikal dengan atom substrat 3

  4. Lanjutan... 2. Skema mekanisme adsorpsi serta Intermediet kompleks-p tri-atomik dan diradikal untuk (a) cis-dietilen dan (b) trans-dietilen 2-klorovinil Si- Cl 109 kkal/mol C-Cl 95 kkal/mol Deklorinasi tunggal vinilin 2-klorovinil vinilin 4

  5. Lanjutan... 3. Skema mekanisme adsorpsi serta intermediet diradikal pada (c) iso-dietilen vinilidin 5

  6. Lanjutan... 4. Geometri 4 kemungkinan adstruktur untuk isomer dikloroetilen di permukaan model 2 x1 cluster Si15H16 • ::> Gambar (a) dan (b) : • 2-klorovinil (disosiasi atom Cl) • ΔE ~2kcal/mol = tidak ada pengaruh secara termodinamika • ::> Gambar (c) dan (d) : • Lebih stabil dibandingkan Gambar (a) dan (b) • ::> Gambar (c) : • Adstruktur vinilin dari deklorinasi dobel dari cis- dan trans-dietilen • ::> Gambar (d) : • Adstruktur vinilidin dari deklorinasi iso-dietilen 6

  7. KESIMPULAN • Struktur isomer menghasilkan produk deklorinasi (vinilidin dan vinilin) • Struktur isomer memiliki distribusi muatan atom berbeda di atom C 7
