Is HCN polar?
Understand the Problem
The question is asking whether hydrogen cyanide (HCN) has a polar or nonpolar molecular structure. To determine this, we need to consider the electronegativity differences between the atoms in the molecule and the molecular geometry.
Answer
Yes, HCN is polar.
The final answer is Yes, HCN is polar.
Answer for screen readers
The final answer is Yes, HCN is polar.
More Information
HCN (Hydrogen Cyanide) has a linear geometry. Nitrogen is more electronegative than both carbon and hydrogen, resulting in a significant dipole moment that does not cancel out, making the molecule polar.
Tips
A common mistake is assuming that a molecule with a linear shape is always nonpolar. It's important to consider the electronegativity differences between atoms and how they contribute to the dipole moment.
