Which of the following is not correct `:`

Options

A. Carbon `-` carbon bond length in `CaC_(2)` will be more than that in `CH_(2)C CH_(2)`
B. `O-O` bond length in `Na_(2)O_(2)` will be more than that in `KO_(2)`.
C. `O-O` bond length in `O_(2)[PtF_(5)]` will be less than in `KO_(2)`
D. `N-O` bond length in `NO` gaseous molecule will be smaller than that bond length in `NOCl` gaseous molecule.

Answer

1

Explanation

In `CaC_(2)` there is `C=C` , while in `CH_(2)C CH_(2)`, there is only `C=C`.
`KO_(2)=K^(+)+O_(2)^(-)`
`" "`Bond order `=1.5`
`Na_(2)O_(2)=2Na^(+)+O_(2)^(2-)`
`" "`Bond order `=1.0`
`O_(2)(Pt F_(6))O_(2)^(+)+[Pt F_(6)]^(-)`
`" "`Bond order `=2.5`
N Bond order `=2.5`
while in `NOCl`, bodn order `=2`
