Which of the following statements are correct ? (I) In ICl_(2)-CIF_(3

1.	Which of the following statements are correct ? (I) In ICl_(2)-CIF_(3) and TeCl_(4), the number of ions pairs (s) of electrons on central atoms are 3,2 and 1 respectively. (II) Amongst CO,CO_(2),CO_(3)^(2-),CH_(2)OH the correct order from the weakest to the strongest carbon-oxygen bond -=CH_(3)OH lt CO_(3)^(2-) lt CO_(2) lt CO. (III) The I^(-),b^(-)idisation of boron in BF_(2) is the same which nitrogen has in CINO molecule.
Answer» Only `(I) & (III)` `(II)` Only `(I) & (II)` `(I),(II) & (III)` Solution : `(II)" ":C-O=1.43Å,C=O" "1.23Å,C=O" "1.09Å` `CO,Coverset(LARR)(-=)=O` partial triple bond character, borid LENGTH is intermediat of `C=O` and `C-=O` bonds `CO_(2),O=C=O,` double bond length partial double bond character, intermediate of `C=O` and `C-O` single bond length.
