Description : Trans-Pent-2-ene is polar while trans-but-2-ene is non polar. Explain.
Last Answer : Ans. In trans-but-2-ene, the dipole moment of two C-CH3 bonds are equal and opposite and hence they exactly cancel out each other. Thus trans-but-2-ene is non polar. In trans-pent-2-ene, ... cancel out each other and hence trans-pent2-ene has a small value of dipole moment and thus is polar.
