The molecular geometry of BrF 5 is square pyramidal with asymmetric charge distribution on the central atom. 3. (Enter your answers in the order given in the skeletal structure from left to . An electron from the 22 orbital and three other electrons from 2p orbitals participate in forming bonds. A) 0 sigma, 1 pi B) 3 sigma, 0 pi There is an overall net dipole of nonzero due to the oxygen atom being more electronegative than the bromine atoms, meaning that the molecule is polar. See the answer. C) 2. It is produced by marine algae. Why don't libraries smell like bookstores? Electron-pair geometry is the direct effect of molecular geometry. How many of the following molecules have sp hybridization on the central atom? List the number of sigma bonds and pi bonds in a triple bond. Which species has the smaller bond angle, H3O+ or H2O?
