Drawing Constitutional Isomers | 4.4 Organic Chemistry

Answer each question based on the video lesson you just watched. No outside knowledge is needed — all answers come directly from the video content.

Show all work step by step. Problems increase in difficulty — start with HDI calculations, then move to systematically drawing and counting constitutional isomers.

These are challenging, exam-level questions that require multi-step reasoning, analysis, and evaluation. Expect to apply the HDI formula, systematically enumerate isomers, and reason about molecular structure — some questions extend beyond the video into related applications.
