Question
### Question 14 of 22 #### Which compound does not contain electrons that can delocalize? - ○ CH₃—C≡C—CH₃ - ○ CH₂=CH=CH₂ - ○ CH₃CH₂COO⁻ - ○ CH₃NO₂ This question is presented on an educational website as part of a larger set, specifically within a chemistry context. The objective is to identify which of the given compounds lacks delocalized electrons. 1. **CH₃—C≡C—CH₃**: This is 2-butyne. The triple bond between carbons suggests the possibility of π-electrons, but the molecule as a whole does not exhibit resonance that involves delocalization. 2. **CH₂=CH=CH₂**: This is 1,3-butadiene. It contains conjugated double bonds that allow for delocalization of electrons across the molecule. 3. **CH₃CH₂COO⁻**: This is the anion form of propionic acid. The carboxylate group (COO⁻) can delocalize electrons between the two oxygen atoms. 4. **CH₃NO₂**: This is nitromethane. The nitro group (NO₂) also allows for the delocalization of electrons through resonance structures. Based on this analysis, the compound **CH₃—C≡C—CH₃** does not contain electrons that can delocalize.
