WebNH3 have B.P = - 33°c which is greater than of PH3 i.e B. P = -83°C! Explanation : We know that in Periodic Table from going up to down electronegativity decreases! This is due to increase in the size of atomic radius. NH3 molecules make strong intermolecular H bonding b/w themselves. WebDec 28, 2024 · NH3 is more polar than PH3 hence NH3 has greater dipole forces and a higher boiling point. Electronegative differences influences the polarity of a bond. The greater the electro negativity difference between bonding atoms, the greater the dipole forces and the greater the boiling point.
