1.	in each of the following sections three organic halogen compunnds arae listed , in the box given entera number (1 to 3) indicating the of reactivity of the desigented (1 is most reactive and 3 is ,east).
Answer» `S_(N^(1))`Substitution by `NaoCOCH_(3) "in methanol"` ` 1. CH_(3)CH_(2)CH_(2)square2. (CH_(3))_(2)CHBrsquare3. CH_(2)=CHCH_(2)_(2)Brsquare` `S_(N^(1))`Substitution byNal in acetone : ` 1. C_(6)H_(5)Cl 2. C_(6)H_(65)CH_(2)Clsquare3. C_(6)H_(5)CHClCH_(3)SQUARE` `S_(N^(1))`Substitution by NaCn in methanol : ` 1. CH_(3)CH_(2)Cl 2. CH_(3)CH_(2)Fsquare3. CH_(3)CH_(2)Isquare` `S_(N^(1))`Substitution by `NaSCH_(3) `in methanol : ` 1. (CH_(3)_(2)CHCH_(2)Brsquare2. CH_(3)CH_(2)CHBrCH_(2)CH_(3)square3. (CH_(3))_(3)CCH_(2)Brsquare` Solution :(a) `1^(@)` resonance stabized transition state will be more reactive . (b) `1^(@)` resonance stabilized transition state will be will more reactice . (c ) GOOD leaving group.
