In SN_(2) reactions, the correct order of reactivity for the following compounds ? CH_(3)CI,CH_(3)CH_(2)CI,(CH_(3))_(3)CHCI"and"(CH_(3))_(3)"CCI" is

Answer»

`CH_(3)CH_(2)Cl GT CH_(3) Cl gt (CH_(3) )_(2)CHCl gt (CH_(3) )_(3)"CCl"`
`(CH_(3) )_(2)CHCl gt CH_(3)CH_(2)Cl gt CH_(3)Cl gt (CH_(3) ) _(3)"CCl"`
`CH_(3)Cl gt (CH_(3) )_(2)CHCl gt CH_(3)CH_(2)Cl gt (CH_(3) )_(3)`CCl
`CH_(3)Cl gt CH_(3)CH_(2) Cl gt (CH_(3) )_(2)CHCl gt (CH_(3) )_(3) `CCl

Solution :`S_(N)^(2)`
Reactivity of `SN^(2) prop (1)/("Steric HINDRANCE ")`
ORDER of reactivity towards `S_(N)^(2)` .
`CH_(3)CIgtCH_(3)-CH_(2)-CI gt (CH_(3))_(2)CH-CI gt(CH_(3))_(3) C-CI`
