SUMMARY
The discussion centers on the Lewis structure of the cation [CH3OH2]+, highlighting that the oxygen atom carries a positive formal charge despite its higher electronegativity compared to carbon. The participant notes that the electronegativity difference between carbon and oxygen is 0.9 on the Pauling scale, indicating a polar covalent bond. The confusion arises from the expectation that the most electronegative atom should hold the negative formal charge, leading to a deeper exploration of Lewis structure rules and the role of lone pairs in stabilizing charges.
