Vedclass · Answer

(D) The basic character of a molecule depends on the availability of the lone pair of electrons on the central atom for donation. In $PH_3$,the lone pair is present in an orbital with high $s$-character,making it less available for donation. In $P(CH_3)_3$,the three methyl groups are electron-donating groups ($+I$ effect),which increase the electron density on the phosphorus atom,making the lone pair more available for donation. Therefore,$P(CH_3)_3$ is a stronger base than $PH_3$.

Which one of the following statements is correct with respect to basic character?
