Which of the following is a polar molecule?
Show Hint
- \( \) O\(_2\)
- \( \) H\(_2\)
- \( \) N\(_2\)
- \( \) HCl
The Correct Option is D
Solution and Explanation
Step 1: Polar molecules have a permanent dipole moment due to the unequal sharing of electrons between atoms in the molecule, leading to a positive and a negative end.
Step 2: Among the options, HCl is a polar molecule because chlorine is more electronegative than hydrogen, which causes an uneven distribution of electron density, creating a dipole moment. The other molecules (O\(_2\), H\(_2\), N\(_2\)) are non-polar because the electron distribution is symmetric in these molecules.
