Keeping the resonance in mind, suggest the hybridization and geometry of the central atoms (only carbon and nitrogen) in the given species.

• A. a. sp³, sp², sp³b. sp³, sp³, sp², sp², sp³c. sp³, sp²(All sp² atoms with trigonal planar and sp³ atoms with tetrahedral geometry).
• B. a. sp³, sp², sp²b. sp³, sp², sp², sp², sp²c. sp², sp²(All sp² atoms with trigonal planar and sp³ atoms with tetrahedral geometry).
• C. a. sp³, sp³, sp³b. sp³, sp³, sp², sp², sp³c. sp², sp²(All sp² atoms with trigonal planar and sp³ atoms with tetrahedral geometry).
• D. a. sp³, sp², sp³b. sp³, sp², sp², sp², sp³c. sp³, sp²(All sp² atoms with trigonal planar and sp³ atoms with tetrahedral geometry).

Answer: (B)
