Select the correct statements :

Options

A. `C-O` bond length of CO molecule is higher than the `C-O` bond length of `CO_(2)`
B. `C-O` bond length of CO molecule is lower than the `C-O` bond length of `CO_(2)`
C. `N-O` bond length of `NO_(3)^(-)` molecule is higher than the `N-O` bond length of `NO_(2)^(-)`
D. `N-O` bond length of `NO_(3)^(-)` molecule is lower than the `N-O` bond length of `NO_(2)^(-)`

Answer

B, C

Explanation

B.O. of CO = 3, `CO_(2)=2," "NO_(3)^(-)=(4)/(3)," "NO_(2)^(-)=1.5,`
B.O. `prop(1)/("B.L.")`
