Question

Which of the following statements is incorrect for writing the Lewis dot structure?

• A. The total number of electrons required for writing the structure are obtained by adding the valence electrons of the combining atoms
• B. Knowing the chemical symbols of the combining atoms and having knowledge of the total skeletal structure of the compound, it is easy to distribute the number of electrons as bonding shared pairs between the atoms in proportions to the total bonds
• C. In general the least electropositive atom occupies the central position in the molecule/ion
• D. After accounting for the shared pairs of electrons for single bonds, the remaining electron pairs are either utilised for multiple bonding or remain as the lone pairs

Answer 1

Answer: (C)

Statement (c) is incorrect. It's correct form is as follows:
In general, the least electronegative atom occupies the central position in the molecule/ion.
Rest other statements are correct.
