Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which molecules have dipole moment? (1) \[CC{{l}_{4}}\] (2) \[{{H}_{2}}O\] (3) \[C{{O}_{2}}\] (4) Cis-1, 2-dichloroetheneA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
The dipole moment of\[CC{{l}_{4}}\]and\[C{{O}_{2}}\]is zero due to symmetrical structure. \[\underset{\mu =0}{\mathop{Cl-\underset{\begin{smallmatrix} | \\ Cl \end{smallmatrix}}{\overset{\begin{smallmatrix} Cl \\ | \end{smallmatrix}}{\mathop{C}}}\,-Cl}}\,\] \[\underset{\mu =0}{\mathop{O=C=O}}\,\] While water\[{{H}_{2}}O\]and cis-1,2-dichloro ethane has dipole moment.You need to login to perform this action.
