Given the correct order of initials ' T ' or ' F ' for the following statements. Use ' T ' if statement is true and ' F ' if it is false

(I) In $NH_{3}$ , the orbital in which lone pair is present is pure orbital

(II) In $F_{2} O_{2}$ , polar as well as non polar both bonds are present

(III) In $IO_{2} F_{2}^{-}$ , one of the π-bond can be formed by dz2 orbital of central atom

(IV) In $HCO_{3}^{-}$ , all C–O bonds are not same

TestHub · Accepted Answer

(I) NH 3 ​ sp 3 -ideally it should be 25% S for lone pair and 75% P . But according to bent rule %S character increases for lone pair. * due to more near the nucleus nature of s-orbital leading to more stability. Only two resonating (identical), relatively stable resonating structure. Option (B) is correct.
