Question

Select one: True or False

1-The mesomeric form of succimer is the active chelating form that is used to chelate trivalent metals through its COOH groups.

2-Anions with large radius particularly those having less than two negative charge are more easily polarized by the small size cations while those of ≥1 charge like sulfide S-2 and selenium Se-2 are much harder to be polarized

3-Covalent bond is encountered in case of NaCl and KBr while ionic bond is encountered with BeCl₂ and BF₃

_{_4-}Besides providing the largest suitable number of valance orbitals for covalent bond formation it can determine the final shape of the molecule for example Sp hybridization leads to a diagonal planner molecule, SP² hybridization while Sp³ hybridization leads a pyramidal (tetrahydral shape)

5-About the underlying compound ( in the images ) , it it’s a calcium complex of EDTA used to treat metal toxicities like pulmbism in order to avoid hypocalcaemia.
