Lewis Structures, VSEPR, Polarity, IM Forces For each of the following molecules, draw the Lewis structure (with resonance structures if applicable), indicate the molecular shapes and bond angles, indicate molecular polarity (if any), and identify the major intermolecular force in each compound. Carbon tetrafluoride NF3 H2CS Carbonate ion BF3

Transcript

00:01 Dear students, the compound in the question is carbon tetrafluoride.

00:04 For this compound, we have to draw its lewis structure, then molecular structure, molecular structure, then shape, molecular structure, or we can say molecular shape, bond angles, then molecular polarity, molecular polarity, then measure intramolecular forces, if any intermolecular force is there.

00:49 Now, carbon tetrafluoride, carbon we know, carbon has six electrons in its outermost orbit, sorry, total carbon has six electrons, so it has four electrons in its outermost orbit, it, electronic conflation is 1 s 2, 2 s 2p 2.

01:10 In the excited state, it's 1 electron gets promoted to the 2p, 1 electron from 2s subcell gets promoted to 2p subcell, so its electronic configuration becomes like this.

01:26 Then it undergoes sp3 hybridization and after sp3 hybridization it forms 4 bonds.

01:35 With 4 fluorine atoms to form carbon -threter fluoride.

01:41 Therefore it has its molecular shape is tetrahedral.

01:46 Molecular shape is tetrahedral.

01:50 Now because molecular shape is tetrahedral, therefore bond angle is 109 degree 28 minute.

02:03 Now we can draw its shape, tetrahedral shape is like this.

02:07 1 fluorine here, 1 fluorine, 1 fluorine.

02:13 So, its angle is 109 .5 degree or 109 degree 28 minute.

02:20 Because the molecule is symmetrical, it is non -polar and its dipole moment is equal to 0.

02:30 Now, we have to see the intramolecular force because it is non -polar, therefore the intramolecular force is simply land...
