Question

Which of the following is strongest base?
a) Mg(OH)2 b) Al(OH)3 c) Si(OH)4 d) NaOH

Answer 1

Answer:

the stronger base is naoh

Answer 2

NaOH is the strongest base.

strong base:- which can dissociate easily and give OH negative ion.

NaOH is ionic compound and it can easily dissociate to give Na+ and OH negative ion.

Also the size of Na is greater than Mg, Al and Si.

So ionization energy of Na is less than these three.

hence it can easily dissociate to give Na+ and OH negative ion.

Ionization energy increases from left to right due to decrease in atomic size and increases in nuclear charge.

So my dear friend ....

THE ORDER OF BOND DISSOCIATION ENERGY IS:----

Na—OH < Mg—OH < Al—OH < Si—OH
