Question

which of the following molecules has highest dipole moment - Pcl5, NH3 , H2S , NF3​

Answer 1

Answer:

Nh3

Explanation:

I don't know their explanation but I know the answer

Answer 2

The molecules has highest dipole moment is $NH_3$.

Explanation:

• The dipole moment in mathematical terms is the product of charge and distance between the atoms.

• In dipole, the shared pair of electron moves towards a more electronegative element.

• In the given options the dipole moment of PCl_5 is 0.

• Among the two $NH_3$ and $NF_3$ the compound having more dipole moment is NH_3.

• In $NF_3$, Flourine being more electronegative attract shared electrons toward itself and thus the net result is 0 because of its structure.

• Whereas in the case of $NH_3$ , nitrogen being more electronegative attract a shared electron towards itself and thus has the highest dipole moment among these.
