Explanation:
Hydrogen cyanide (HCN)
The molecular geometry of HCN is linear. The compound is polar in nature.
As Carbon is bonded to two atoms, it follows the molecular geometry of AX2. And as per VSEPR theory, molecules covered under AX2 have a linear molecular geometry.
Hence Hydrogen Cyanide has linear molecular geometry.
True, and I'm confused on what you are asking for the bottom piece
