trans-$2$-Pentene

Vedclass · Answer

(B) molecule possesses a permanent dipole moment if it is polar,meaning it has an asymmetric distribution of charge.$2, 2$-Dimethylpropane (neopentane) is highly symmetric ($T_d$ point group),resulting in a net dipole moment of $0$.$2, 2, 3, 3$-Tetramethylbutane is also highly symmetric,resulting in a net dipole moment of $0$.trans-$3$-Hexene is symmetric across the double bond,so the dipole moments of the alkyl groups cancel out,resulting in a net dipole moment of $0$.trans-$2$-Pentene is asymmetric because the alkyl groups attached to the double-bonded carbons are different (one is a methyl group and the other is an ethyl group). Therefore,the dipole moments do not cancel out,and it possesses a permanent dipole moment.
