H-bond to water???? mc

1.  The H-bonded water around an ionic substance tends to ___________________ ___; and the H?
bonded water around nonpolar solutes tends to _______________.
 
A. Inhibit ionization; promote hydrophobic interactions
B. Inhibit ionization; inhibit hydrophobic interactions
D. Promote ionization; not impact hydrophobic interactions
E. Promote ionization; promote hydrophobic interactions

I'm gonna go ahead and say (C) because I really don't think it inhibits ionization because water dissociates and can become OH- or H3O+ which technically requires ionization. Check out the attachment for reference.

What did you put?

I'd say it promotes ionization

I'm going with:


D. Promote ionization; not impact hydrophobic interactions


Water is a polar molecule, thus when ionic substances are in the presence of water, the more electronegative oxygen molecules (have a greater positive charge) will pull anions from the ionic substance and the cations of the ionic substance will bond with the neighbouring hydrogens.

(Dang, that came from my memory...studying is working!! Lol).

This question was seriously killing me!

what about E


Promote ionization; promote hydrophobic interactions

cause its exposed to non polar and in non polar solution it promotes a formation of cage like structure with non polar facing inward


any one.. WOULD ANY ONE TELL ME PLEASEEE ?  D or E WHICH ONE IS IT THAT'S WHERE I AM LOST

I believe it's E.

Water doesn't impact hydrophobic interactions; it impacts hydrophilic ones because it's a polar molecule.  In order to promote hydrophobic interactions, a substance has to have a lipid component because lipids are insoluble in water, and thus hydrophobic.

Hope that helps.

E is final

You just submitted it?
