H2S is the ans.because in H2S sulfur is the more electronegative and so bears a negative charge & secondly u assige the oxidation state.oxidies are always 2- & acidic hydrogen are 1+ third u determine the oxidation number of the central atom by adding the charge of the central atom with the charges of the other atoms.which gives u the charge of the entire molecule. Mathematically we have S+2(+1)=0 and s+2=0 so therefore s=-2. Thanks
