Final answer:
A) True. To complete the electron-dot structure of inosine, one must illustrate all of the molecule's valence electrons as either bonding pairs or lone pairs while ensuring the structure conforms to experimental evidence and chemical rules.
Step-by-step explanation:
The question asks to complete the electron-dot structure of inosine, showing all lone-pair electrons. An electron-dot structure, also known as a Lewis structure, represents the valence electrons in an atom or molecule. Each dot in the structure represents a valence electron, with lone pairs being shown as pairs of dots and bonds between atoms being shown as lines or pairs of dots between the atomic symbols.
For inosine, the Lewis structure would have to account for all the valence electrons of the constituent atoms and correctly represent them either as bonding pairs or lone pairs. Although the question content provided does not directly relate to inosine, the principles of creating a Lewis structure would apply. For example, if inosine had a central atom surrounded by five electron groups with two bonding pairs and three lone pairs, these repulsions would be minimized by arranging them in the corners of a trigonal bipyramid. This information is instrumental in comprehending the 3D structure of molecules.
It is crucial to take experimental studies into account, as sometimes the Lewis structure may not depict the actual electron configuration, such as the presence of unpaired electrons in oxygen molecules. Therefore, when drafting the electron-dot structure of a complex molecule like inosine, one must ensure it aligns with experimental evidence and established chemical rules.
