The decreasing order of C-C bond length in overset(4)(C )H_(3)- overse

1.	The decreasing order of C-C bond length in overset(4)(C )H_(3)- overset(3)(C )H_(2)- overset(2)(C )H= overset(1)(C )H_(2) is……
Answer» `C_(4) - C_(3) GT C_(2) - C_(1) gt C_(3) - C_(2)` `C_(3) -C_(2) gt C_(2) -C_(1) gt C_(4) -C_(3)` `C_(2) -C_(1) gt C_(4) - C_(3) gt C_(3)-C_(2)` `C_(4) -C_(3) gt C_(3) -C_(2) gt C_(2)-C_(1)` SOLUTION :Inductive effect DECREASES as we MOVE away from (C= C) `:. (C_(4)-C_(3)) gt (C_(3)-C_(2)) gt (C_(2)-C_(1))`
