Re: HOCl vs HOI

yes, because HOCl is more stable. Mainly because the O–H bond in HOI is stronger than the O–H bond in HOCl. Making HOCl more likely to donate a proton.

Re: Cisplatin

The Cisplatin bonds with two guanine molecules in DNA which prevents the DNA from functioning. Also if it was transplatin it would only make one bond and would not be effective.

I hope this helps :0

Re: “Soapy” feel of bases

The soapy feel is associated with the base's ability to dissolve oils and fatty acids on your skin which removes friction, leading to a slippery/soapy feel.

Re: Transition Metal in naming

The transition metal does not have a suffix so it should go later the name. I hope that helps.

Re: Orbital Overlap

The orbital that have head-on overlap leads to a sigma bond which is is a strong bond. Especially when compared to a pi bond; formed with two atoms with overlapping p orbitals.

Re: Bonds vs Shapes

I believe at its base, stronger bonds would increase boiling point. However, the strength of the bonds in the molecule could be entirely based off the molecular structure. It's a combination of both that controls the boiling point, viscosity, etc.

Re: Dipole moments

If the molecule in question is completely symmetric than the dipole moment will cancel itself out.

Re: Position of Lone Pairs in H20

I believe the two lone pairs on the top of the oxygen, creating the bent shape, is because of the overall polarity of the molecule. The two hydrogen atoms both have a partial positive helps maintain the polarity and therefore would repulse the two lone pairs. Not certain but I hope that helps.

Using this equation: E(photon) - E(removed e-) = E(kinetic). you can solve for the difference in energy for kinetic.
