Which of the following compound does not react with acety1 chloride ?A. `CH_(3)NH_(2)`B. `(CH_(23))_(2)N`C. `(CH_(3))_(2)NH`D. both (2) and (3)

Answer» Correct Answer - B
Primary and secondary amines can react with acid chlorides such as acety1 chloride to from substituted amindes in which `-Ci` has been replaced by th `-NHR` or `-NR_(2)` group
`CH_(3)NH_(2)+CH_(3)COCIoverset(-HCI)rarrCH_(3)NH-overset(O)overset(||)C-CH_(3)`
`(CH_(3))_(2)NH+CH_(3)COCIoverset(-HCI)rarr(CH_(3))_(2)NH-overset(O)overset(||)C-CH_(3)`
Tertiary amines (although basic and hence nucleophilic)fail to yield amides because they cannot lose a proton (to stabilize the product) a fter bonding themselves to electron-deficient carbon
`(CH_(3))_(3)N+CH_(3)COCI rarr`No reaction .
