Considering cis-but-2-ene and trans-but-2-ene, which statement about their dipole moments is correct

Q: What is the correct answer for NCERT11?

The correct answer is B. Cis-but-2-ene is more polar than the trans form. In cis-but-2-ene, the dipole moments of the C-CH3 bonds do not cancel out, resulting in a net dipole moment (0.33 Debye). In trans-but-2-ene, the C-CH3 bond dipoles are in opposite directions and cancel each other out, leading to a dipole moment of almost zero.

Q: What are the options for this NCERT11 question?

A. Both cis and trans forms have a significant dipole moment. · B. Cis-but-2-ene has a dipole moment of 0.33 Debye, while trans-but-2-ene has a dipole moment of almost zero. · C. Trans-but-2-ene has a dipole moment of 0.33 Debye, while cis-but-2-ene has a dipole moment of almost zero. · D. Neither cis nor trans forms have a dipole moment.
