JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Amongst \(BeF _{2}, BF _{3}, H _{2} O , NH _{3}, CCl _{4}\) and \(HCl\), the number of molecules with non-zero net dipole moment is ...... .
- A \(3\)
- B \(2\)
- C \(1\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(3\)
Step-by-step Solution
Detailed explanation
\(BeF _{2}, BF _{3}\) and \(CCl _{4} \Rightarrow \mu_{\text {net }}=0\) \(H _{2} O , NH _{3}\) and \(HCl \Rightarrow \mu_{\text {net }} \neq 0\)
