Question

Which has highest dipole moment?

• A. $^{H}_{H}\big> C=O$
• B. $^{H_3C}_{H_3C}\big> C=C\big
• C. $^{H}_{H_3C}\big> C=C\big
• D. $^{Cl}_{H_3C}\big> C=C\big

Answer 1

Answer: (A)

$^{H}_{H}\big> C=O$

Answer 2

Due to the large difference in electronegativity of carbon and oxygen atoms, there is a greater charge separation, hence highest dipole moment is of HCHO among the given compounds .
