What is the molecular shape of HCN? bent linear angular trigonal pyramidal<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The molecular shape of HCN (Hydrogen Cyanide)<\/strong> is linear<\/strong>.<\/p>\n\n\n\n

Here\u2019s why:<\/p>\n\n\n\n

    \n
  1. Lewis Structure of HCN<\/strong>: The molecule consists of a central carbon (C) atom bonded to a hydrogen (H) atom and a nitrogen (N) atom. The carbon atom forms a triple bond with nitrogen, and a single bond with hydrogen.<\/li>\n\n\n\n
  2. Electron Groups<\/strong>: The carbon atom has two electron groups around it \u2014 one from the triple bond with nitrogen and the other from the single bond with hydrogen.<\/li>\n\n\n\n
  3. VSEPR Theory (Valence Shell Electron Pair Repulsion)<\/strong>: According to VSEPR theory, electron pairs (bonding or non-bonding) around a central atom arrange themselves in a way that minimizes repulsion. In the case of HCN, there are only two bonding pairs around carbon, which would place them as far apart as possible, resulting in a linear<\/strong> arrangement.<\/li>\n\n\n\n
  4. Bond Angles<\/strong>: In a linear geometry, the bond angle between the atoms is 180\u00b0<\/strong>.<\/li>\n\n\n\n
  5. Molecular Shape<\/strong>: The presence of just two bonding pairs and no lone pairs on the central carbon atom dictates a linear shape, not angular, bent, or trigonal pyramidal.<\/li>\n<\/ol>\n\n\n\n

    In summary, because the electron pairs around carbon are spread out in a linear arrangement, the molecular geometry of HCN is linear, with a bond angle of 180\u00b0. The triple bond between carbon and nitrogen is particularly strong and influences the overall shape, leading to this geometry.<\/p>\n\n\n\n
