Respuesta :
Answer: A. dipole
Explanation:
Dipole can be defined as the separation of the equal and opposite charges present in the molecule via ionic bonding. The water molecule comprising of two molecules of hydrogen being positively charged and one molecule of oxygen being negatively charged are connected via ionic bonding thus water molecule is an example of dipole molecule. There is unequal distribution of the electrical density throughout the molecule.
The polar molecule results in a dipole when equal but opposite charges are present in two regions.
Dipole:
Dipole arises when a molecule have opposite and equal charge in the ends.
For example - water molecule
In water molecule Oxygen is negatively charged and hydrogen have low electronegativity, this difference in electronegativities arise dipole in molecule.
Therefore, the polar molecule results in a dipole when equal but opposite charges are present in two regions.
