1.	The total number of compounds having atleast one bridging oxo group among the molecules given below is ……….. . N_(2)O_(5),N_(2)O_(3),P_(4)O_(6),P_(4)O_(7),H_(4),P_(2),O_(5),H_(5)P_(3)O_(10),H_(2)S_(2)O_(3),H_(2)S_(2)O_(5)
Answer» SOLUTION :These are `N_(2)O_(5)` , `P_(4)O_(6)` , `P_(4)O_(7)` (one P=O in `P_(4)O_(6)`), `H_(4)P_(2)O_(5)` , `H_(5)P_(3)O_(10)` If `N_(2)O_(3)` is ALSO INCLUDED, then total number of compounds is
