JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Number of compounds/species from the following with non-zero dipole moment is _______.
[\(\mathrm{BeCl}_2, \mathrm{BCl}_3, \mathrm{NF}_3, \mathrm{XeF}_4, \mathrm{CCl}_4, \mathrm{H}_2 \mathrm{O} \mathrm{H}_2 \mathrm{~S}, \mathrm{HBr}\), \(\mathrm{CO}_2, \mathrm{H}_2, \mathrm{HCl}\)]
- A \(3\)
- B \(5\)
- C \(7\)
- D \(8\)
Answer & Solution
Correct Answer
(B) \(5\)
Step-by-step Solution
Detailed explanation
Polar molecule: \(\mathrm{NF}_3, \mathrm{H}_2 \mathrm{O}, \mathrm{H}_2 \mathrm{~S}, \mathrm{HBr}, \mathrm{HCl}\) \((\mu \neq 0)\) Non Polar molecule: \(\mathrm{BeCl}_2, \mathrm{BCl}_3, \mathrm{XeF}_4, \mathrm{CCl}_4, \mathrm{CO}_2, \mathrm{H}_2\) \((\mu=0)\) So answer is \(5\) .
