A) How many lone pairs are on the central atom in BCl3?
Express your answer numerically as an integer.
B)How many lone pairs are on the central atom of BrF3?
Express your answer numerically as an integer.
Write Lewis structure, molecular designation, molecular shape,
ideal bond angle, number of bonding electron pairs, number of
electron lone pairs in the following molecules:a. [6 pts] COBr2.b. [6 pts] [H3O]+.
I need the # electron pairs groups around the central atom
for:
OS2, CS2, PF6-, ICl4-, XeOF4, BF4-, H3O+, AlH4-, Nf3, PH4+, SeO3
2-, SnCl2, SeCl4, CH2O, NO2-, ICl2-, BrF5, and AlCl6 3-.
Which assumption about the space occupied by nonbonding (lone
pair) electron pairs is mpst consistent with the experimental bond
angles: do nonbonding pairs occupy more, less, or the same amount
of space as bonding pairs?
Plese be thorough and ledgible in your answer
Find point number of electron groups around central atom?
Polarity? Number of Lone pairs for central atom? Lewis dot
structure? Approximate bond angles? Electron pair arrangement
around central atom/shape of the molecule? Hybridization of central
atom? Symmetry elements and Points groups of compounds below.
a) NF3
b) XeO3
c) SCl2
