Decreasing order of C-C bond length is (I)C_2H_6 (II)C_2H_2 (III)C_ – InterviewSolution

1.	Decreasing order of C-C bond length is (I)C_2H_6 (II)C_2H_2 (III)C_6H_6 (IV)C_2H_6
Answer» IV gt III gt I gt II I gt II gtIV gt III II gt I gt IV gt III IV gt I gt III gt II Solution :Bond length `prop 1/"Bond order"` Bond order =`"Bonding -antibonding ELECTRON"/2` Bond order is highest for `C_2H_6` so it has MINIMUM bond strength
