Can you tell how?
X and y bonds have resonance so partial double bond character...
But x double bond has more stable resonance so it is shortest
For 36-C^+ forms at most stable position then hydride shift
Is 36 B?
Yeah, was just gonna say what he said.
Can you also tell why x is more stable?
Because in its resonance structure, the x wala O gets negative charge and y wala O gets positive charge. Negative charge on O is more stable na bro.
Ya got it thanks
