$P(CH_3)_3 > PH_3$

Vedclass · Answer

(A) The basicity of phosphines depends on the availability of the lone pair on the phosphorus atom.In $P(CH_3)_3$,the three methyl groups exert a $+I$ (inductive) effect,which increases the electron density on the phosphorus atom.This makes the lone pair more available for donation compared to $PH_3$,where no such electron-donating groups are present.Therefore,the correct order of basic character is $P(CH_3)_3 > PH_3$.

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