These questions contains, Statement-I (assertion) and Statement-II (reason).
Statement-I : Buta-1,3-diene is less stable than Penta-1, 4-diene.
Because
Statement-II : Buta-1,3-diene has greater number of resonating structures and delocalised electron cloud,
Options:
Answer:
D
Solution:
Explain Question:
Asking about the correct relationship between A & R regarding dienes.
Concept:
This question is based on resonance effect.
Solution:
Buta-1,3-diene is more stable than penta-1,4-diene due to resonance effect. Resonance effect is the stabilizing effect because π–electron cloud delocalize over more atoms.
Hence statement-I is false but statement-II is true.
