The correct statement among the following is :
is pyramidal and less basic than .
nis planar and less basic than .
is planar and more basic than .
is pyramidal and more basic than .
Electronegativity of Nitrogen family -
Gradually decreases down the group. More electronegative than group 14
Positive oxidation state of Nitrogen family -
Shows +3 and +5 oxidation states (except N2)
Stability of +3O.S increases down the group due to inert pair effect
+3 when only p electron are involved and +5 when all valence five (s and p) electrons are involved
Negative oxidation state of Nitrogen family -
Exhibits -3 O.S, decreases on moving down the group
is planar & less basic than .
Because, lone pair of Nitrogen-atom is in unhybridised p-orbital & it overlaps with d-orbital of si-atom, thus planar in nature.
is less basic than as lone pair of electrons on nitrogen-atom is in conjugation with all Si-atoms.
