Answer» in AlCl³ ,Al is positively chargedsince Al+ Cl-³because only 3election is present in 3s² 3p¹ orbital,so it give its electron to chlorine and form Al+. since chlorine has only 1 electron left to complete its octate so 3 chlorine atom combine with 1 aluminium atom to form Al+ Cl-³ or Alcl³so due to POSITIVE charge and vacant 3 orbital it exhibit greater power TOWARD NEGATIVE colloid while on other side K⁴[Fe(CN⁶)] has no such REQUIREMENTS so it is wrong answer and correct answer is AlCl³ |
