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 $\mathbf{C}-C>Si-Si>Ge-Ge>Sn-Sn)$
