1.	Consideringthe elements F , C1 , O and N thecorrectorderof theirchemicalreactivityin termsofoxidisingproperty is : ( a) F gt C1 gt O gt N ( b) F gt O gt C1 gt N ( c)C1 gt F gt O gt N ( d)O gt F gt NC1
Answer» Solution :WITHINA periodthe oxidisingcharacter increases from leftto right . ThereforeamongF, O and Noxidisingpowerdecreasesin the order : `F gt Ogt N`. Howeverwithin a groupoxidising POWER decreases from top to bottom. Thus F is STRONGER oxidisingagentthan C1. Furtherbecause Ois moreelectronegativethan C1 thereforeO is a strongeroxidisingagent than C1 Thusoveralldecreasingorderof oxidisingpower is `: F gt O gt C1 gt N` i.e.,OPTION( b) is correct.
