Anomalous behaviour of carbon

Question

Statement I : Catenation power of C > Si < Ge $≃$ Sn.
Statement II : Bond Enthalpy of C-C > Si-Si > Ge-Ge > Sn-Sn.

Moderate

A

Statements I and II are correct
B

Statement I is correct and statement II is incorrect
C

Statement I is incorrect and statement II is correct
D

Statements I and II are incorrect

Solution

Catenation power $\propto$ Bond Enthalpy;
Catenation power of C > Si > Ge $≃$ Sn.
Bond Enthalpy of C-C > Si-Si > Ge-Ge > Sn-Sn.
