Question

determine the molecular geometry of n₂o (oxygen is terminal).
tetrahedral
trigonal pyramidal
linear
bent
trigonal planar

Explanation:

• First, draw the Lewis structure of \(N_2O\). The central atom is \(N\). The Lewis structure is \(N\equiv N - O\).
• Then, use the VSEPR (Valence - Shell Electron - Pair Repulsion) theory. The central \(N\) atom has 2 electron - group (one triple bond and one single bond can be considered as two electron - groups in VSEPR model for geometry determination).
• According to VSEPR theory, when the number of electron - groups around the central atom is 2, the molecular geometry is linear.

Answer:

C. linear
