The molecules having dipole moment are __________.
(i) 2,2-Dimethylpropane
(ii) trans-Pent-2-ene
(iii) cis-Hex-3-ene
(iv) 2, 2, 3, 3 – Tetramethylbutane
The answer is the option (ii) trans-Pent-2-ene & (iii) cis-Hex-3-ene
Explanation: (ii) Because of different groups attached, trans-Pent-2-ene shows net dipole moment.
(iii) Here, both groups are inclined to each other at an angle of and hence has a resultant dipole moment. Thus, cis-Hex-3-ene shows a dipole moment.
