A molecule that has a partial positive charge on one end and a partial negative charge on the other end is a. a dipole. b. binary molecule. c. linear molecule. d. nonpolar molecule.

a. a dipole.

Explanation:

A dipole -

The term Dipole, can be bifurcated as di + pole, i. e., two poles.

Hence, any species or compound where two poles i. e., a positive and a negative is possible, is termed to as a dipole.

For example, in water molecule,

The more electronegative atom, i. e., oxygen attains a negative charge and correspondingly, the hydrogen atom have a positive charge, and hence can give rise to a dipole.
