$HClO_3$

Vedclass · Answer

(D) $SH_6$ does not exist because sulfur cannot expand its coordination number to $6$ with hydrogen due to steric hindrance and bond energy constraints.$HFO_4$ does not exist because fluorine is the most electronegative element and cannot exhibit positive oxidation states.$FeI_3$ is unstable because $Fe^{3+}$ is a strong oxidizing agent and $I^-$ is a strong reducing agent,leading to the spontaneous reduction of $Fe^{3+}$ to $Fe^{2+}$ and oxidation of $I^-$ to $I_2$.$HClO_3$ (chloric acid) is a stable and well-known oxoacid of chlorine.
