NHSO is a ionic bond a nonpolar covalent bond or a polar covalent bond?

Answer 1

It is thio nitrous acid an unstable compound there are polar covalent bonds in it and hence soluble in water giving thio nitrite ion and hydrogen ion.. S=N-OH = S=N-O- + H+

Answer 2

NH3 (ammonia) is a polar covalent bond because nitrogen and hydrogen have different electronegativities, causing an unequal sharing of electrons. This results in a slight negative charge on the nitrogen atom and a slight positive charge on the hydrogen atoms.
