Question

which of the alkali hydrixides is the most basic?
a)KOH
b)NaOH
c)LiOH
d)CsOH​
please tell this it is very urgent.

Answer 1

Answer :-

We have got the alkali hydroxides :-

a) KOH ( Potassium Hydroxide )

b) NaOH ( Sodium Hydroxide )

c) LiOH ( Lithium Hydroxide )

d) CsOH ( Cesium Hydroxide )

Now as we know these are the hydroxides formed by Alkali Earth metals i.e First Group elements.

Now the property to compare basicity

⟩ The Basic Nature increases as we go down the periodic table.

Reason :- Due to increase in the size of the atom the electronic transfer gets easier.

Now Elements of the first Group :-

H , Li , Na , K , Rb , Cs , Fr

So as we see Cs ( Cesium ) Comes at 2nd Position from down.

Hence :- CsOH is most basic in the given Question.
