1.	Compound (A) contains Cl in its structure and Cl has uninegative and unipositive carge in compound (A). On long standing, compound (A) undergoes auto oxidation and form (B) and ( C), but in presence of CoCl_(2) catalyst it forms B and D. B is also produced when compound (A) reacts with H_(2)S gas. Which of the following statements are correct about (A)?
Answer» It is a powerful bleaching AGENT, bleaching action is due to oxidation It is used in the manufacture of dynes, drugs and organic compounds such as ` C Cl_(4),CHCl_(3),DDT` and refrigerants It is used in preparation of poisonous gases such as phosgene `(COCl_(2))`, tear GAS `(C Cl_(3)NO_(2))`,MUSTARD gas `(ClCH_(2)CH_(2)SCH_(2)CH_(2)Cl)` It is used in sterlising DRINKING water. Solution :`A rarr CaOCl_(2),B rarr CaCl_(2),C rarrCa(ClO_(3))_(2),D rarr O_(2)`
