Why was the hydrogen atom able to attach to the oxygen atom but not the chlorine atom???

Chlorine has a higher electronegativity, but as it has a large atomic radius the electron density is spread out over a large area. This means that the electron density is too low to form proper hydrogen bonds, and will only be attracted via dipole-dipole attraction.

hi,

the answer is d.indefinite shape but definite volume, let go oogle u out

hope this !

the increase of protons   hope this
