JEE Advance - Chemistry (1992 - No. 11)
The molecules that will have dipole moment are
2, 2-dimethylpropane
trans-2-pentene
cis-3-hexene
2,2,3,3-tetramethylbutane
คำอธิบาย
2, 2-dimethylpropane and 2, 2, 3, 3 - tetramethylbutane are symmetrical molecules so their net dipole moment is zero. (b) and (c) have resultant dipole moment.
