Consider only the atoms when assigning symmetry. While lone pairs influence shapes, molecular symmetry is based on the geometry of the atoms. 1) H2O 2) p-Dichrlorobenzene 3) Ethane 풀이:p.93 Exercise 4.1 Using a point in a three dimensional Cartesian coordinate system..

AsH3 should have the smallest angle, since it has the largest central atom. - This minimizes the bond pair-bond pair repulsions and allows a smaller angle. - Arsensic is al..

Miessler) 풀었던 부분만 올립니다 (쪽수: 번역판 기준) p. 56 Example 3.1 SCN- In the thiocyanate ion, SCN-, three resonance structures are consistent with the electron-dot method, as shown in Fig 3.3. Structure A has only negative formal charge on the nitrogen atom, the most electronegative atom in the ion. Structure B has a single negative charge on the S, which is less electronegativ..
