1.	Arrange the following carbanions in order of their decreasing stability. (A) H_(3)C-C-=C^(-) (B) H-C-=C^(-) (C) H_(3)C-bar(C)H_(2)
Answer» `A gt B gt C` `B gt A gt C` `C gt B gt A` `C gt A gt B` Solution :`+I` effect decreases the stability of CARBON ANION. SINCE `CH_(3)` group has +I effect. In B, there is no +I effect, in A , +I effect is there but distance is more from negatvely charged carbon and in C, +I effect `(CH_(3))` direct to NEGATIVELY charged carbon.
