Question

what is the bond angle of this linear molecule? h - c≡n:

Explanation:

For a linear molecule, the bond angle is determined by its molecular geometry. In a linear structure, the atoms are arranged in a straight line. The formula for bond angles in simple molecular geometries (like linear) is based on minimizing electron - pair repulsions. In a linear molecule, the two regions of electron density (bonding pairs in this case for \(H - C\equiv N\)) are farthest apart when the angle between them is \(180^{\circ}\).

Answer:

\(180^{\circ}\)
