Bond energy : Energy required to break a...

Bond energy : Energy required to break a bond (equal to the energy released when a bond is formed) is named bond energy. Its unit is Kcal/mole. Stability of bond energy 00 % s character `oo(1)/(% "P character")oo "bond order" oo(1)/("bond length")`
Higher is the number of bonds at a place, higher is the bond energy.
Which are true in terms of bond energy ?
(i) `CH_(3) -Fgt CH_(3) -Clgt CH_(3)- Brgt CH_(3)-1 `
(ii) `H_(3) C - O lt H_(3) C - CH_(3) lt CH_(2) = CH -O - CH_(3)`
(iii) `CH_(3) - CH_(2) -O - CH_(3) lt CH_(2) =CH-O -CH_(3)`
(iv) `C- N gt N gt C = N`
(v) `CH_(3) - CH_(2)- NH_(2) lt CH_(2) = CH -NH_(2) lt CH= C -NH_(2)`
