Dipole moment order of which of the following pairs of molecules is not correct?
- A \(\mathrm{HF}>\mathrm{HCl}\)
- B \(\mathrm{H}_2 \mathrm{~S}>\mathrm{CO}_2\)
- C \(\mathrm{NH}_3>\mathrm{NF}_3\)
- D \(\mathrm{CH}_4>\mathrm{CHCl}_3\)
Answer & Solution
Correct Answer
(D) \(\mathrm{CH}_4>\mathrm{CHCl}_3\)
Step-by-step Solution
Detailed explanation
\(\mathrm{CH}_4\) has a tetrahedral shape and is symmetrical so, its dipole moment is zero. But in \(\mathrm{CHCl}_3\) presence of the one atom produce small dipole moment. Thus, dipole moment of chloroform is greater than methane.
