Phosphine ph
WebJul 3, 2014 · In the analogous case for phosphorus (phosphine, $\ce{PH_3}$), the $\ce{H-P-H}$ bond angle is 93.5 degrees. This angle indicates that the phosphorus atom is almost unhybridized (the bond angle would be 90 degrees if it were completely unhybridized). The 3 bonds from phosphorus to hydrogen roughly involve the three 3p orbitals on phosphorus … WebThe name "phosphine" was first used for organophosphorus compounds in 1857, being analogous to organic amines (NR 3). The gas PH 3 was named "phosphine" by 1865 (or earlier). Structure and properties. PH 3 is a trigonal pyramidal molecule with C 3v molecular symmetry. The length of the P−H bond is 1.42 Å, the H−P−H bond angles are 93.5°.
