Statement I : Catenation power of C > Si < Ge ≃ Sn.
Statement II : Bond Enthalpy of C-C > Si-Si > Ge-Ge > Sn-Sn.
Statements I and II are correct
Statement I is correct and statement II is incorrect
Statement I is incorrect and statement II is correct
Statements I and II are incorrect
Catenation power ∝ Bond Enthalpy;
Catenation power of C > Si > Ge ≃ Sn.
Bond Enthalpy of C-C > Si-Si > Ge-Ge > Sn-Sn.
