Answer» Solution :(i) Since `I^(-)`ION is a better leaving group than Brion, THEREFORE, `CH_(3) I`REACTS faster than `CH_(3)Br` . (ii) On STERIC consideration, `1^(@) ` halides are more reactive than tert-alkyl halides in `S_(N)2`REACTIONS. Therefore, `CH_(3)Cl`will react at a faster rate than`(CH_(3))_(3) C Cl `. |
