Rank from most conductive to least conductive: alcl3, c6h12o6, kbr, c3h7ooh ? ?

The order is:

AlCl₃ > KBr > C₃H₇COOH > C₆H₁₂O₆

Explanation:

A compound is conducting in nature (in soluble form) if it is ionic.

More the ions produced by a compound more the conductive the compound is.

In the given compounds C₆H₁₂O₆ is non electrolytic or non ionic. It will dissolve in water and will not furnish any ion thus it will be non conducting (least)

C₃H₇COOH: It is a weak electrolyte and will dissociate very less in water and thus it will be conducting but less than a strong elecrolyte.

KBr and AlCl₃ both are ionic and will dissociate completely however AlCl₃ will produce four ions while KBr will give only two ions per molecule.

Hence AlCl₃ is more conducting

The order is:

AlCl₃ > KBr > C₃H₇COOH > C₆H₁₂O₆
