Question

determine the electron geometry of $n_2o$ (oxygen is terminal).
trigonal planar
tetrahedral
hexahedral
pentahedral
linear

Explanation:

To determine the electron geometry of \(N_2O\) (with oxygen as terminal), we first look at the Lewis structure. The central atom (in this case, one of the nitrogen atoms which has a linear arrangement of electron - groups around it). The electron - group geometry is determined by the number of electron - groups (bonding and non - bonding) around the central atom. For \(N_2O\), the central atom has 2 electron - groups (double or triple bonds count as one electron - group for electron - geometry determination). According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when the number of electron - groups (\(n = 2\)), the electron geometry is linear.

Answer:

linear
