Valence Shell Electron Pair Repulsion Theory -- Molecular Structure VSEPR theory predicts which shape for the molecular structure of the following molecules or molecular ions? (i.e. the arrangement of only the bonded atoms about the central atom) bent (or angular) ICl2 ion (The central atom is I.) tetrahedral SeCl2 molecule (The central atom is Se.) tetrahedral 104 ion (The central atom is I.) 2 pts Submit Answer Incorrect.

Answer 1

20 Il in having central atom as I Iodine (I) hoe 7 valence elections in its outermost shell and there is a negative charge on Illi , making 8 electrons in total. Out of these 8 elections 2 elections will make a single bond with chlorine. atoms, and the remaining 6 elections will form 3 love pair. Therefore, coordination number is 5 12 Bond pair with chlorine and 3. lone pairs). So its hybridization is dsp , having trigonal pyramidal geometry. And its shape es linear. o sodine He

Toy molecule , having central atom as I Iodine (I) has 7 valence elections in its entermost shell and adding the negative charge on Ion « total elections gets to 8. There are 4 oxygen atoms which will form double bond with iodine, thus 8 lections of iodine will make double bonds with 4 oxygen atoms. Thers, coordination no. of rodine es 4 with sp² hybridization and tetrahedral geometry. And its shape is tetrahedral
