Rank the Following Compounds in Order of Increasing Stability: Rank The Following Compounds In Order Of Increasing Stability.
Chemical stability refers to the ability of a compound to resist changes in its chemical composition and structure. Factors affecting stability include molecular structure, functional groups, and the presence of catalysts or inhibitors.
Compound Properties
| Compound | Molecular Formula | Functional Groups | Structural Features |
|---|---|---|---|
| Compound A | CH4 | Alkane | Tetrahedral |
| Compound B | C2H4 | Alkene | Double bond |
| Compound C | C2H2 | Alkyne | Triple bond |
| Compound D | C6H6 | Aromatic | Benzene ring |
Stability Ranking, Rank the following compounds in order of increasing stability.
- Compound A (CH4) : Most stable due to strong C-H bonds and tetrahedral structure.
- Compound D (C6H 6) : High stability due to resonance and aromaticity.
- Compound C (C2H 2) : Less stable than A and D due to the high reactivity of the triple bond.
