Reason: Metals at the top of series are very reactive and metals at the bottom are least reactive. Answer (b) Metals at the top of the series are very reactive and therefore, they do not occur free in nature.

NettetCalculation reaction energy for the propagation step of mono-chlorination of methane (referring to the corresponding bond energies in Table 9.1.) Solution: Step 1: H — CH 3 + •Cl → CH 3 • + H — Cl. The H — CH 3 bond broken, absorb energy, so +440 kJ. The H — Cl bond formed, release energy, so – 432 kJ. ΔH 1 = +440 + (-432) = +8 kJ
