Draw a Lewis structure for (a) PH4+; (b) C2F4; (c) SbH3.
Here, we are going to draw the Lewis structure of the molecules.
Lewis structure is the representation of the valence electrons that form the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
The rules for drawing a Lewis structure.Draw the correct skeletal structure for the molecule.Calculation of the total number of valence electronsDistribution of the electrons among the atoms to attain octets (or duets for H)If there is any atoms that is lack an octet, then form double or triple bonds to make them octet.
The electronic configuration of H(Z=1) 1s1
Valence electrons in H =1 e-
The electronic configuration of P(Z=15) [Ne] 3s23p3
Valence electrons in P =5e-
Thus, total valence electrons in PH4+ =(5 + 41 -1) =8 e-
The Lewis structure of PH4+ is given below:
