The order of decreasing stability of the carbanions (CH_(3))_(3) C^(-), (CH_(3))_(2) CH^(-) (II) , CH_(3) CH_(2)^(-) (III) , C_(6) H_(5) CH_(2)(IV) is

Answer»

`I gt II gt III gt IV`
`IV gt III gt II gt I `
`IV gt I gt II gt III`
`I gt II gt IV gt III`

Solution :`C_(6) H_(5) CH_(2) (IV) gt CH_(3) CH_(2) (III) gt (CH_(3))_(2) CH^(-) (II) gt (CH_(3))_(3) C^(-) (I)`
