Phosphine (PH3) reacts with borane (BH3) as follows: PH3 1 BH3 - H3P i BH3 (a) Which of

Problem 11.13

Phosphine  reacts with borane  as follows:

(a) Which of the illustrations below depicts the change, if any, in the orbital hybridization of P during this reaction?

(b) Which depicts the change, if any, in the orbital hybridization of B?

                                                             Step by step solution

Step 1 of 2

(a)

In figure A, three hybridized orbitals change to four hybridized orbitals. So, there is a change in hybridization.

In figure B, four hybridized orbitals remain the same on both sides. So, there is no change in hybridization.

In figure C, five hybridized orbitals change to four hybridized orbitals. So, there is a change in hybridization.

In figure D, four hybridized orbitals change to five hybridized orbitals. So, there is a change in hybridization.
