Question

= CH₂=CH-OH resonating
structured​

Answer 1

Answer:

Most stable, more number of covalent bonds, each carbon and oxygen atoms has an octet and no separation of opposite charge.

II: Negative charge on more electronegative atom and positive charge on more electronegative atom and positive charge on more electropositive atom.

III: Does not contribute as oxygen has positive charge and carbon has negative charge, hence least stable.

Answer 2
