water-soluble collagens insoluble in water peptide chains arranged in Answer Bank often function as enzymes or transport proteins keratins hemoglobin peptide chains highly folded into spherical shapes generally function in structure and support

Draw a valid Lewis dot structure and determine the VSEPR molecular geometry for each central atom for each of the following. When appropriate, draw all applicable resonance structures.  For species in which formal charges are not all zero, determine the nonzero formal charges on the relevant atoms.

Please send me the question in 20 minutes it's very urgent plz

Give detailed Solution with explanation needed..give correct answer

The name of the following molecule is: B

Solve EXACTLY like the exmaple. Example attached

The molecule shown here is in water. H. :: H.

Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.) O trigonal pyramidal shape, nonpolar O trigonal planar shape, nonpolar O tetrahedral shape, polar O trigonal pyramidal shape, polar O trigonal planar shape, polar

Check the box next to each molecule on the right that has the shape of the model molecule on the left: molecules model (check all that apply) ? alo to O BrF O NH, You can drag the slider to rotate the model molecule. O CH,O O CF4 O None of the above Note for advanced students: the length of bonds and size of atoms in the model is not necessarily realistic. The model is only meant to show you the general geometry and 3D shape of the molecule.
