Molecules of hydrogen chloride (HCI) are shown in diagram X and diagram Y. Which of the following describes which diagram shows attractive forces, and why?
A Diagram X, because the dashed lines show the attraction between nonmetal atoms that have a similar attraction to electrons.
B
Diagram X, because the dashed lines show that the positive end of one molecule is attracted to the negative end of an adjacent molecule.
С
Diagram Y, because the dashed lines show the attraction between nonmetal atoms that have a similar attraction to electrons.
D
Diagram Y. because the dashed lines show that the positive end of one molecule is attracted to the negative end of an adjacent molecule.

Sagot :

Since HCl is a polar molecule, there will be attraction between the the positive end of the dipole in one molecule and the negative end of the dipole in another molecule.

Polar molecules are those molecules in which there is a high difference in electronegativity between the bonding atoms. This results in the appearance of partial charges in the molecule. One end of the molecule has a partial negative charge and the other end of the molecule has a partial positive charge.

Since HCl is a polar molecule, there will be attraction between the positive end of one molecule and the negative end of another molecule.
