In which of the following bonds, does the cl atom have the highest electron density? latex: o-cl o − c l latex: n-cl n − c l latex: br-cl b r − c l latex: h-cl h − c l latex: s-cl

hey there!:

Electron density on Cl atom depends on electronegativity difference between Cl and other bonded atom. If the electrnegativity difference is more then Cl has greater electron density, that menas if the bonded atom has less electronegativity then bonded electrons are more attracted by Cl and it has greater electron density.  

Among the five atoms which are bonded to Cl atom H has low electronegativity. So in H-Cl two bonded electrons are closer to Cl atom as it has greater electronegativity than H. This results more electron density on Cl atom.

Hence in H-Cl bond Cl atom have the highest electron density

Hope this helps!
