Consider the molecules PH, and PMe,. If these molecules were classified as Lewis bases and were to react with BH,, then: (a) The adduct formed with PH, would have the strongest B–P 3 bond. (b) The adduct formed with PH, would have the longest B-P bond. (c) The adduct formed with PH, would have a double bond between P and B, B=P, because PH, is sterically unhindered. (d) The adduct formed with PMe, would have the strongest B-P bond. (e) The adduct formed with PMe, would have the weakest B-P bond because PMe, is very sterically hindered.
