An explanation is given for the difference in lengths of the axial and equatorial bonds in molecules such as PCl5 and ClF3 whose structures are based on the trigonal-bipyramidal arrangement of five valency-shell electron pairs. The fact that in molecules with a central atom with a valency shell...
Hybrid orbitals are created by the mixing of s and p orbitals to help us create degenerate (equal energy) bonds.sp³, made from s + 3p gives us 4 hybrid orbitals for tetrahedral geometry and 109.5 degree bond angles.Sp², made from s + 2p gives us 3 hybrid orbitals for trigonal pl...

Select all of the following molecules that would be expected to experience dipole-dipole attractions. CO2 CH2Cl2 PCl3 SeCl4 XeF4 CF4 PCl5 BCl3 BrF3 What bond angles do you expect for the following? The O-S-O angle in SO4^2- What bond angles do...
How many lone pairs of electrons are in the central atom of the molecule? What is the electron pair geometry of the molecule? What is are the bond angles at the central atom of the molecule How many covalent bonds are predicted for an atom of si? How man...
ΔΔH for H for each step each step 2) C + 4H + 2Cl CH 3 Cl + HCl Forming the bond should be the reverse of the process of breaking the bonds. ΔH should be equal in magnitude and opposite in sign from the bond enthalpy ΔH 2 = - [3 * D(C – H) + D(C – Cl) +...
