Molecular Geometry of N2O

The video tutorial explains two main methods to determine the molecular geometry of N2O: VSEPR theory and AXN notation. VSEPR theory suggests that atoms spread out to minimize electron pair repulsion, leading to a linear structure for N2O. AXN notation further confirms this by showing that N2O is an AX2 type, which is linear with bond angles of 180 degrees. The tutorial concludes with a summary of these concepts.
