Title: Allegra (Fexofenadine HCL) Post by: jho44 on Apr 22, 2012 I'm having a little trouble drawing the lewis structure of this drug because this drug is admisnistered as an ammonium salt so i will need to draw it in the ionized form of the drug with the anion.
Title: Re: Allegra (Fexofenadine HCL) Post by: lewis on Apr 22, 2012 You have to draw the lewis structure for this:

Title: Re: Allegra (Fexofenadine HCL) Post by: jho44 on Apr 22, 2012 From there, I have to draw the skeletal line structure which is what you have there but again, he wants it in the ionized form of the drug with the anion. Then I have to circle the chiral carbon of the ionized form of the drug and the list goes on which I can't do because I'm stuck at the first step of how to draw it in the ionized form.
