For BCl_(3), AlCl_(3) and GaCl_(3) the increasing order of ionic chara

1.	For BCl_(3), AlCl_(3) and GaCl_(3) the increasing order of ionic character is
Answer» `BCl_(3) LT AlCl_(3) lt GaCl_(3)` `GaCl_(3) ltAlCl_(3)lt BCl_(3)` `BCl_(3) lt GaCl_(3) lt AlCl_(3)` `AlCl_(3) lt BCl_(3) lt GaCl_(3)` Solution :The electronegativity decreases in ordr : `B(2.0) GT Ga(1.6) gt Al (1.5)`, therefore ,ioniccharacter of theirchloridesincreasesin the REVERSEORDER, i.e., `BCl_(3) lt GaCl_(3) lt AlCl_(3)` and henceoption(c ) is correct.
