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.. 2023. 11. 7.

NH3, PH3, or AsH3 b. c. NO2- or O3 d. ClO3- or BrO3- 풀이: a. 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.. 2023. 11. 7.

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.. 2023. 11. 7. [무기화학] 2장. 원자 구조 연습문제 풀이 Inorganic chemistry (Gary L.
