11) pick the best Lewis construction for NO3 . A) B) C) D) E) 12) Identify the sheer number of electron teams around a molecule with a trigonal bipyramidal form. A) 1 B) 2 C) 3 D) 4 E) 5 13) Determine the electron geometry (eg) and molecular geometry(mg) of BC13. A) eg trigonal planar, mg trigonal planar C) eg tetrahedral, D) eg-trigonal planar, mg curved E) eg trigonal bipyramidal, mg trigonal bipyramidal 14) Determine the electron geometry (eg) and molecular geometry (mg) of SiF A) eg-tetrahedral, mg-trigonal pyramidal B) eg octahedral, mg square planar C) eg trigonal bipyramidal, mg-trígonal pyramidal D) eg tetrahedral, mg curved E) eg tetrahedral, mg tetrahedral

11) Lewis frameworks where the main atom with 8 electrons

sufficient reason for minimal or no formal fees tend to be more steady. Ergo,

response A

12) No. of electron teams around main atom in trigonal

bipyramidal is 5. thus response is E

13) BCl3 contain 3 electron sets around main boron atom.

Therefore both electric and molecular geometry is trigonal planar.

for this reason response is A

14) SiH4 have 4 electron sets around main boron atom. Ergo

both electric and molecular geometry is tetrahedral. Therefore response

is E
