Ncert Exercises & Solutions

The molecules having dipole moment are ________

1. 2,2-Dimethylpropane

2. trans-Pent-2-ene

3. cis-Hex-3-ene

4. 2,2,3,3 - Tetramethylbutane

(2, 3)

Thus, trans-pent-2-ene show net dipole moment because different group attached and cis-Hex-3-ene show dipole moment because both groups

(C_{2} H_{5})

are inclined to each other to angle of

60 °

therefore have a finite resultant.
