Which of following is most Acidic in aqueous solution :-
Which of following is most Acidic in aqueous solution :-
Acidic nature of hydrides increases down the group in p-block
so H2Te will be most acidic among given options.
Upvote If ionisation energy of an element is as follows :
X → X+ + 1e–; 1E1 = x kJ/mol
X+ → X2+ + 1e– ; 1E2 = 1.5 x kJ/mol
X2+ → X3+ + 1e– ; IE3 = 15x kJ/mol
This element may have the electronic configuration :-

This element may have the electronic configuration :-
A jump is seen after 2nd Ip so Ve– = 2
hence configuration would be ns2
Upvote SO3 (s) exist as cyclic trimer ⇒ S3O9
→ sp3, so all bond π–bonds would be of pπ–dπ so pπ–pπ bond = 0
pπ–dπ bonds = 6
Upvote Which of the following have one lone pair on the central atom ?
<!-- [if !supportLists]-->(I) <!--[endif]-->NH3
<!-- [if !supportLists]-->(II) <!--[endif]-->SF4
<!-- [if !supportLists]-->(III) <!--[endif]-->XeOF4
<!-- [if !supportLists]-->(IV) <!--[endif]-->XeF6
