ParaGraph (Bonding)

Bent's rule is consistent with VSEPR theory.
Accord. to Bent's rule, the more electronegative substituent attaches itself to hybrid orbital that contains more p-charach./less s-character.

1) Molecule/ion inwhich Bond angle is less than 109⁰-
A)N⁺F₄ B)CCl₄ C) ClO₄^- D)None

2) Select the pair in which both have different hybridisation, but same molecular geometry-
A)BF₃, BrF₃ B) ICl₂^-, BeCl₂
C)BCl₃, PCl₃ D) PCl₃, NCl₃

3) Find the species which is not perfectly planar-
A) ^. CH₃ B) ^. CHF₂
C) :CF₂ D) ^. NO₂

(A single dot repesents an electron/free radical)

btw, Doubt is only with 3), posted all due to the paragraph...[1]
