Select the wrong chemical reaction among the following:

Options

A. `MnO_(2) + 4HC1 to Mncl_(2) + Cl_(2) + 2H_(2)O`
B. `8NH_(3) + 3Cl_(2) to 6NH_(4)Cl + N_(2)`
C. `2NaOH + Cl_(2) to 2NaCl + H_(2) + O_(2)`
D. `2Ca(OH)_(2) + 2Cl_(2) to Ca(OCl)_(2) + CaCl_(2) + 2 H_(2)`

Answer

C

Explanation

NaCl and NaClO are formed when `Cl_(2)` reacts with cold dilute NaOH.
`Cl_(2) + 2NaOH overset("cold")to NaCl + NaClO + H_(2)O`
With hot concentrated NaOH, NaClO formed is rapidly decomposed to give NaCl and `NaClO_(3)`
`3Cl_(2) + 6NaOH overset("hot") 5NaCl + NaClO_(3) + 3H_(2)O`
