I want to thank your team (Jeff) for finding a new writer when you were unable to reach my existing writer to revise my paper. I appreciate your professionalism and efforts. Thanks
There is no difference between molecular shape and . They both mean the same thing.
However, there is a difference between molecular shape and electron geometry.
The Lewis structures of CH₄, NH₃, and H₂O are:
They all have four electron pairs about the central atom, so they are all sp³ hybridized.
Their orbitals all point about 109° towards the corners of a tetrahedron. We say that the electron geometry is tetrahedral.
Note that CH₄ has no lone pairs, NH₃ has one lone pair, and H₂O has two lone pairs. The molecular geometry considers only the arrangement of the bonds. It ignores the lone pairs.
In CH₄, the C-H bonds all point towards the corners of a tetrahedron at angles of 109.5°. We say that the molecular geometry and the electron geometry of CH₄ are each tetrahedral.
In NH₃, the three N-H bonds point towards three of the corners of a tetrahedron. The molecule looks like a three-legged stool sitting on the floor with the N atom as a seat on the top. It is like a pyramid with a triangular base.
We say that the molecular shape of NH₃ is trigonal pyramidal, but its electron geometry is still tetrahedral.
In H₂O, the two O-H bonds point towards two of the corners of a tetrahedron. The molecule looks like an obtuse angle.
We say that the molecular shape of H₂O is bent, but its electron geometry is still tetrahedral.
