Product (X and Y) of the following reactions (1 and 2) are (1) 2NaOH _ ( Cold and dilute ) + C l _ 2 → NaCl + X + H _ 2 O (2) 6NaOH _ ( Hotand conc.) + 3C l _ 2 → NaCl + Y + 3 H _ 2 O

Correct answer: B. X = NaOCl and Y = NaCl O _ 3 C l _ 2 + 2NaO H _ ( dil . ) cold → NaCl + NaOCl _ ( X ) + H _ 2 O 3C l _ 2 + 6NaO H _ ( conc . ) hot → 5NaCl + NaCl O _ 3 _ ( Y ) + 3 H _ 2 O

Product (X and Y) of the following reactions (1 and 2) are

(1)

\mathop{2NaOH}_{( \text{Cold and dilute} )} + C{l}_{2} \to NaCl + X + {H}_{2}O

(2)

\mathop{6NaOH}_{( Hotand conc.)} + 3C{l}_{2} \to NaCl + Y + 3{H}_{2}O

Options

A $X = NaCl{O}_{3}$ and $Y = NaOCl$
B $X = NaOCl$ and $Y = NaCl{O}_{3}$
C $X = NaHCl{O}_{3}$ and $Y = NaOCl$
D $X = NaCl{O}_{3}$ and $Y = NaHCl{O}_{3}$

Correct answer

B. $X = NaOCl$ and $Y = NaCl{O}_{3}$

Step-by-step solution

C{l}_{2} + 2NaO{H}_{( dil . )}\overset{cold}{\to}NaCl + \mathop{NaOCl}_{( X )} + {H}_{2}O

3C{l}_{2} + 6NaO{H}_{( conc . )}\overset{hot}{\to}5NaCl + \mathop{NaCl{O}_{3}}_{( Y )} + 3{H}_{2}O
