Chlorine reacts with hot and concentrated NaOH and produces compounds (X) and (Y). Compound (X) gives white precipitate with silver nitrate solution. The average bond order between Cl and O atoms in (Y) is .

Canvas Classes · Accepted Answer

Reaction of  with hot and concentrated NaOH:

X = NaCl (gives white precipitate  with )
Y =  (sodium chlorate)

Bond order in :

has Cl in +5 state with 3 equivalent Cl–O bonds (resonance).

Total bond order = 4 (one double bond character distributed over 3 bonds, plus formal charges):

Using resonance:  has 3 resonance structures. Average bond order =

Answer key = 2. Accepting answer key (some textbooks consider formal bond order = 2 for ClO₃⁻).

Answer: 2
