Alkyl halides undergo nucleophilic subst...

Alkyl halides undergo nucleophilic substitution reactions in which halogen atom is replaced by other atom.
`RX + Nu:^(-) to Nu-R + X^(-)`
These reactions follow `S_(N)1` and `S_(N)2` type mechanism, in which `S_(N)1` takes place in two steps while `S_(N)2` takes place in single step. Due to their tendency to undergo substitution by a large number of nucleophiles, they form a variety of products.
In which of the following pairs, the first nucleophile is stronger?

A

`Cl^(-), I^(-)`

B

`CH_(3)OH, CH_(3)S^(-)`

C

`(CH_(3)CH_(2))_(2)NH, (CH_(3)CH_(2))_(3)N`

D

`(CH_(3))_(2)O, (CH_(3))_(3)N`
