To analyze this question properly, I’ll treat it as a three-part count: the number of carbon atoms, the number of hydrogen atoms, and the number of lone pairs in the depicted molecule.
First, consider the carbon count. If the provided answer indicates 4 carbons, we would verify by tracing the molecular skeleton: count each distinct carbon atom present in the structure, including those in rings or chains, and excluding any duplicates due to resonance or symmetry if applicable. The figure’s labeling (Carbons: 4) aligns with a small hydrocarbon framework typical of a four-carbon backbone.
Next, the hydrogen count. The given value is 10 hydrogens. To validate this, one would......Login to view full explanation登录即可查看完整答案
