Phosphoryl iodide is used in the preparation of organophosphorus derivatives and phosphate esters. select the lewis structure for poi3 that minimizes formal charges.

The Lewis Structure of Phosphoryl triiodide with each element having minimum formal charge is shown below,..

In this structure all elements have zero formal charge.

As, Formal charge is given as,,

Formal Charge  =  # of Valence e⁻s - [ e⁻s in lone pairs + 1/2 bonding e⁻s]

For P,

Formal Charge  =  5 - 0 + 10/2  =  0

For O,

Formal Charge  =  6 - 4 + 4/2  =  0

For I,

Formal Charge  =  7 - 6 + 2/2  =  0

Tropical easterlies is mostly likely your answer correct me if i’m wrong

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
