Each carbon has a linear electron geometry and molecular geometry (180 degrees for both HCC angles). The geometry of the molecule can be described in two ways: 1) Electron Geometry–the geometry that takes lone pairs and atoms into account (hint: there is are only 5 different electron geometries) and 2) Molecular Geometry– the geometry that ignores lone pairs and only takes atoms into account (there are 13 of these).

We'll determine the C2H2 molecular geometry with respect to the Carbon on the right (the other Carbon atom will have the same shape since they are symmetrical).Looking at the C2H2 Lewis structure we can see that there are two atoms attached to the Carbon of interest and that there no lone pair electrons. The lewis structure looks linear, but it can't be because it has 4 atoms, can it? (See also Figure.)
