The correct order of the magnitude of bond energy ( kJ/mol\mathrm{kJ} / \mathrm{mol} ) of the central C−C\mathrm{C}-\mathrm{C} bond in the following compounds is (i) CH2=CH−\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}2_2 (j) Me3C−CPh3\mathrm{Me}_3 \mathrm{C}-\mathrm{CPh}_3 (k) MeCO−CO−Me\mathrm{MeCO}-\mathrm{CO}-\mathrm{Me} (l) CH≡C−C≡CH\mathrm{CH} \equiv \mathrm{C}-\mathrm{C} \equiv \mathrm{CH}

Options

  1. Ak>i>l>j\mathrm{k}>\mathrm{i}>\mathrm{l}>\mathrm{j}
  2. Bj>k>l>i\mathrm{j}>\mathrm{k}>\mathrm{l}>\mathrm{i}
  3. Ci>j>k>l\mathrm{i}>\mathrm{j}>\mathrm{k}>\mathrm{l}
  4. Dl>i>k>j\mathrm{l}>\mathrm{i}>\mathrm{k}>\mathrm{j}
