Among the given species the one which contains weakest carbon - oxygen bond : `CO_2,CH_3COO^(-),CO,CO_3^(2-)`

Among the following which one has weakest carbon-halogen bond ?

Among the following which one has weakest carbon-halogen bond?

Among the species CO_(2),CH_(3)COO',CO,CO_(3)^(2-)HCHO which has the veakest carbon-oxygen bond

Which of the following statements are correct ? (I) In ICl_(2), ClF_(3) and TeCl_(4) , the number of lone pair(s) of electrons on central atoms are 3,2 and 1 respectively. (II) Amongst CO,CO_(2),CO_(3)^(2-),CH_(3)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 hybridisation of boron in BF_(3) is the same which nitrogen has in ClNO molecule.

Among the species CO_2, CO_3^(2-), CH_3COO^(-) , CO, HCHO which has longest carbon-oxygen bond
