Statement 1: The chlorine atom in HCl develops a partial negative charge and hydrogen atoms develop a partial positive charge.

Statement 2: A chlorine atom with a lower electronegativity attracts the shared pair of electrons towards its nucleus.

Q. What type of attraction occurs between the partial positively charged hydrogen atom in one water molecule and the partial negatively charged oxygen atom in another water molecule?

Q. Dipole moments : $HCl\left(1.03D\right)$ and $HI\left(0.38D\right)$. compare the magnitude of the partial charge on hydrogen atom in $HCl$ with that on the hydrogen atom of $HI$. If it is assumed that the partial positive and negative charges are central on the hydrogen and halogen atoms, respectively, the distance between charge centers are calculated to be $1.27$ and 1.61$\dot{A}$ for $HCl$ and $HI$, respectively :

Q. Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself.

Q. Chlorine atom in $NaCl$ gets a unit negative charge:

Q. Electronegativity is the tendency of an atom in a molecule to attract the shared pair of electrons towards itself.
