Not longest carbon to carbon bond but the longest bond in general(it is a mistake) Circle Ethanol < -------------------------- lewis structure for C​2​H​2 b https://secure-media.collegeboard.org/apc/ap10_chemistry_q5.pdf http://chemsanchez.weebly.com/uploads/5/8/3/5/58356363/day_3_bonding_frqs.pdfhttp://chems anchez.weebly.com/uploads/5/8/3/5/58356363/day_3_bonding_frqs.pdf Replace F with A . Reword I didn't choose particulate diagrams B, F, and G. I didn't choose B because each compound only had one atom. After reading the names of the compounds, I knew that each compound needed at least two different atoms or compounds within the molecule. Because B only had one element, which wasn't bonded to anything, I rules out this answer choice. I didn't choose diagram F because magnesium is positively charged, nitrate is negatively charged, oxygen is negatively charged, and hydrogen is positively charged. Because the magnesium is positively charged, the negatively charged oxygen will be attracted to the magnesium according to coulomb's law. However, the diagram shows the magnesium attraction the hydrogen, which defies Coulomb's law. I didn't choose diagram G because it resembled a solid and the only solid was solid calcium chloride. Calcium chloride could only have one Calcium atom in the compound, but diagram G has two, so diagam G is incorrect.
