Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE
हिन्दीConsider the following statements regarding the Lewis approach and formal charges: (A) Generally, the lowest energy Lewis structure is the one with the smallest formal charges on the atoms. (B) In writing Lewis structures, each positive charge on a polyatomic ion means the subtraction of one electron from the total valence electrons. (C) Lewis dot structures successfully predict the three-dimensional shapes of polyatomic molecules. (D) In the nitrite ion (\( \text{NO}_2^- \)), the total number of valence electrons is 18. Choose the correct answer from the options given below:
Correct answer · Option 4
(A), (B) and (D) only
Explanation
(A), (B), and (D) are correct. (C) is incorrect because Lewis structures do not represent the actual shapes of molecules.
