Question 7 - 01 February - Shift 2

The correct order of bond enthalpy $(kJ mol^{-1})$ is

(1) $Si-Si>C-C>Sn-Sn>Ge-Ge$

(2) $Si-Si>C-C>Ge-Ge>Sn-Sn$

(3) $C-C>Si-Si>Sn-Sn>Ge-Ge$

(4) $C-C>Si-Si>Ge-Ge>Sn-Sn$

Show Answer

Answer: (4)

Solution:

Formula: Bond Enthalphy Order

(Bond enthalpy order $\mathbf{C}-C>Si-Si>Ge-Ge>Sn-Sn)$
