Ph3 Lewis Structure. Remember that hydrogen H only needs two valence. Therefore start with the structure analysis of triphenylphosphine and borane using the VSEPR theory and then determine the Lewis acid and base.
A ICl b PH3 c P4 each P is bonded to three other P atoms d H2S e N2H4. Count the valence electrons in your trial structure 8. In case of PH3 P has 5 valence electrons add into 3H monovalent atoms and divide them by two so answer came 4 sp3.
Hydrogen group 1 but we have three of them for a total of 8 valence electrons.
Two free electrons are left as a free electron pair to fill the octet. Click to see full answer. In case of PH3 P has 5 valence electrons add into 3H monovalent atoms and divide them by two so answer came 4 sp3. The P atom is in the center with 6e- making the bonds to the three hydrogens.
