1 answer:
Answer:
A. O=C=O and O≡C−O
Explanation:
Resonance:
When the electron distribution on the molecule become uneven like one molecule have more electron compare to other.Resonance occurs due to overlap of the orbitals.When electron flow through pi system then resonance occurs.
So the option A is correct.
A. O=C=O and O≡C−O

Answer: Option (C) is the correct option.
Explanation:
When two intermediate chemical equations are combined, the same substance that appears in the same phase can be canceled out, provided that it is a reactant in one intermediate reaction and a product in the other reaction.
For example,
....(1)
.........(2)
Cancelling the common species in both the equations as follows.
Therefore, on addition we get the equation as follows.
