If M.P. of Hydrogen is 13.96K then M.P. of deuterium will be
Options:
Answer:
C
Solution:
The melting point (M.P.) of a substance is related to its molecular mass and intermolecular forces. Deuterium (D₂) has a higher molecular mass (4 amu) than hydrogen (H₂, 2 amu). This leads to stronger London dispersion forces in D₂, resulting in a higher melting point. Therefore, the M.P. of deuterium will be higher than 13.96 K.
The M.P. of deuterium is approximately 18.7 K.
