Here, option B and C will be correct. Let's eliminate all options first, Here A and D both follows 18 electron rule... So they are stable.. They do not gives substitution reaction. While in option B and D there are 20 electron. In which we are removing Cp5 and adding NO(linear), which will contribute the 3e. So... If we substrate the Cp and add NO then both B and C will follows 18 electron rule... So both ans should be correct.
sir in ans key only c why?
may be more stable is considered
ok sir thanks ❤
