Which substance has a dipole moment?

Question

Which substance has a dipole moment? (A) CCl 4 (B) CH 2 Cl 2 (C) C 2 Cl 2 (D) C 2 Cl 4

Tardigrade Admin · Accepted Answer

CH 2 Cl 2 is similar to CH 4 (tetrahedral) but it has three different bond angles, HCH , HCCl , ClCCl which are close to but not equal to 109.5°. Since, electroegativity of Cl > C > H, the bond moments do not cancel and the molecule has a dipole moment

Q. Which substance has a dipole moment?

$CC l_{4}$

$C H_{2} C l_{2}$

$C_{2} C l_{2}$

$C_{2} C l_{4}$

$C H_{2} C l_{2}$ is similar to $C H_{4}$ (tetrahedral) but it has three different bond angles, $H C H, H CCl, ClCCl$ which are close to but not equal to $109. 5^{\circ}$ . Since, electroegativity of $Cl > C > H$ , the bond moments do not cancel and the molecule has a dipole moment

CCl4​

CH2​Cl2​

C2​Cl2​

C2​Cl4​

CH2​Cl2​ is similar to CH4​ (tetrahedral) but it has three different bond angles, HCH,HCCl,ClCCl which are close to but not equal to 109.5∘. Since, electroegativity of Cl>C>H, the bond moments do not cancel and the molecule has a dipole moment

$CC l_{4}$

$C H_{2} C l_{2}$

$C_{2} C l_{2}$

$C_{2} C l_{4}$

$C H_{2} C l_{2}$ is similar to $C H_{4}$ (tetrahedral) but it has three different bond angles, $H C H, H CCl, ClCCl$ which are close to but not equal to $109. 5^{\circ}$ . Since, electroegativity of $Cl > C > H$ , the bond moments do not cancel and the molecule has a dipole moment
