HCN is a linear molecular geometry. What is the polarity of HCN molecule?
|
|
Polar molecule
|
|
|
Non-polar molecule
|
Explanation:
Detailed explanation-1: -In the HCN molecule, there is a partial, positive charge on the hydrogen atom and there is a partial negative charge on the nitrogen atom because of the electronegativity difference. Therefore, it is a polar molecule.
Detailed explanation-2: -It is polar covalent, ‘cause the eletronegativity of nitrogen is way higher than that of carbon and hydrogen, but still, you must look at the molecule geometry. Its geometry is linear, wich means the angles between the molecules of hydrogen-carbon-nytrogen is 180°.
