Chlorine reacts with sodium hydroxide to give NaCl and NaClO where oxidation states of Cl are different. This reaction along with the oxidation states is given below:

This option is incorrect. Ethane (C_2H_6):

Ethane is an alkane. It primarily reacts with chlorine via free radical substitution, typically under UV light or high temperatures.

This option is incorrect. Potassium iodate (V) (KIO_3):

Potassium iodate is an oxidizing agent where iodine is already in a high oxidation state (+5). While it can participate in redox reactions, its reaction with chlorine is not a typical scenario where chlorine itself disproportionates to give two different oxidation states. Chlorine is also an oxidizing agent. If a reaction occurs, it would likely involve the oxidation state of iodine changing, or a very specific and less common reaction of chlorine. It does not commonly lead to chlorine producing two products with different oxidation states from itself.

Chlorine reacts with sodium hydroxide to give NaCl and NaClO where oxidation states of Cl are different. This reaction along with the oxidation states is given below.

This option is incorrect. Potassium hydroxide (KOH):

Potassium hydroxide is a strong base, chemically very similar to sodium hydroxide. It also undergoes disproportionation reactions with chlorine gas, identical to those with sodium hydroxide:

* With cold, dilute KOH:

Cl_2 (g) + 2KOH (aq) \rightarrow KCl (aq) + KClO (aq) + H_2O (l)
