HCl

Postby tierra parker 1J » Wed Nov 07, 2018 1:04 pm

in lecture, lavelle was talking about how HCl has a permanent dipole moment and I was wondering how do we know that.

HCl molecules have a dipole moment because the hydrogen atom has a slight positive charge and the chlorine atom has a slight negative charge. Since Cl is more electronegative, electrons are drawn to it more than they are to the H.

There is an electronegativity difference between the H and Cl atoms. Cl is more electronegative and thus attracts electrons more, causing the dipole.

HCl has a permanent dipole moment because H becomes slightly positive because it gives its electron to Cl which becomes slightly negative.

HCl has a permanent dipole because Cl is one of the most electronegative element while H isn't. So, Cl has the tendency to pull all the electron, creating a dipole.

HCl has a permanent dipole moment because of its polarity. Cl is more electronegative, so Cl side always has a slight negative charge.

Chlorine is electronegative and H gives it an electron, making it slightly more positive and thus chlorine is more negative, creating a dipole moment
