how do you find dipole moment when bond length given

to be exact, they ask find % ionic char which is uobs/ucalc and they give observed as 1.2D and bond length to be 1A how do u find the calc mu

Don’t think this is in the syllabus

uh but they have asked this imy coaching the dipole moment of AB molecule is given by 1.2 D and A - B the bond length is 1­Å then % ionic character of the bond is

probably in advanced syllabus, idk calculated dipole moment would be charge * distance, same as physics formula the distance is given as bond length for the charge i guess since its A(+) and B(-) the positive charge is e and the negative charge is also e so use e for the charge

they multiply with 4.8 x 10^-10 esu what is that number
Nimboi

esu is how many joules? or coulombs, i mean?

simplybearOP4d ago
its a unit of charge yes 3.33 x 10^- uhh 10 yes C

they've just converted e from 1.6 * 10^(-19) coulombs to its esu value

i heard it was hard

yeah yeah but i managed it pretty badly math especially i could've done much better

hmm well gl for april 💯 +solved @Nimboi
