Question

The molecule having largest dipole moment among the following is:

• A. $CH{I}_3$
• B. $C{H}_4$
• C. $CHC{l}_3$
• D. $CC{l}_4$

Answer 1

The correct option is A $CH{I}_3$

${CHI}_3$ is the moleclue having largest dipole moment. Because, $C-Cl$ bonds in ${CHCl}_3$ are more polar than $C-I$ bonds in ${CHI}_3,{CH}_4$ and ${CCl}_4$,have zero dipole moments because of regular tetrahedron nature.
