A. O=C=O and O≡C−O
B. N≡N and Br−Br
C. N≡C− and N≡C−H
D. O=N−F and N=O−F
A. O=C=O and O≡C−O
B. N≡N and Br−Br
C. N≡C− and N≡C−H
D. O=N−F and N=O−F
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:

2.
Explanation:
The more stable the ionic compound, the more is it lattice energy.
- The more the charge on the cation and the anion, the greater is the lattice energy.
- The less the size of the cation and the anion, the greater is the lattice energy.
Scandium oxide () is an oxide in which
behaves as cation and
behaves as anion.
The compounds which has higher lattice energy than scandium oxide are:
1 .
This is because the charge are same on the cation and the anion as in the case of the Scandium oxide but the size of the cation is smaller than
. Thus, this corresponds to higher lattice energy.
2.
This is because the charge on the cation is greater than that of
and also the size of the cation
is smaller than
. Thus, this corresponds to higher lattice energy.
