Answer:
It is polar
Explanation:
Hydrogensulfate is an oxoanion of sulphur , conjugate base of a sulfuric acid and conjugate acid of a sulfate
Please see the structure of HSO4 in the attached image
Polar molecules have electronegativity difference between the bonded atoms.
In case of Hydrogensulfate, hydrogen is positive while sulfate is negative ion.
Electronegativity of hydrogen is 2.2 while that of sulfur and oxygen is 2.58 and 3.44 respectively
Thus, it is a polar molecule.
