Q9.83CP - Chemistry: Molecular Nature Of Matter And Change

Question

What would be the formula for the simplest compound formed from (a) phosphorus and chlorine, (b) carbon and fluorine, and (c) iodine and chlorine? 

Step-by-Step Solution

Answer

The simplest compound and their respective Lewis structures are given below

(a)One of the simplest compounds of phosphorus and chlorine is ${\mathbf{PCl}}_3$

(b) One of the simplest compounds of carbon and fluorine is ${\mathbf{CH}}_4$

(c) One of the simplest compounds of iodine and chlorine is $\mathbf{ICl}$

Phosphorous trichloride

  

Phosphorous has five valence electrons. It needs three electrons to complete its octet. It shares three of its electrons with three chlorine atoms which require one electron to complete the octet

Carbon Tetrafluoride

 

Carbon has 4 valence electrons. It needs four electrons to complete its octet. It shares four of its electrons with four fluorine atoms which require one electron to complete the octet

 

Iodine Chloride

 

 

Seven valence electrons constitute iodine. It needs 1 electron to complete its octet. It shares one of its electrons with one chlorine atom which requires one electron to complete the octet.
