Imines or enamines are selectively reduced to `1^(@)` or `2^(@)` amines with:

A

a.`NaBH_(4)`

B

b.`LAH`

C

c.`NaCNBH_(3)`

D

d.`NaAiH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`NaCNBH_(3)` reduces imines or enamines `(RCH=NH, or RCH=NH-R^(1)) or R_(2)C=NH or R_(2)C=NHR')` to `1^(@)` or `2^(@)` amines. So the answer is `(c )`.

Assertion : The order of basicity of amines in the gaseous phase follows the order : 3^(@) amine gt 2^(@) amine gt 1^(@) amine gt NH_(3) Reason : Amines have an unshared pair of electrons on nitrogen atom due to which they behave as Lewis base .

Alkyl isocyanides (Roverset(o+)(N)-=overset(ɵ)(C )) are reduced to 2^(@) amines (R-NH-CH_(3)) with:

Amines are derivatives of ammonia and are classified as 1^(@), 2^(@) , and 3^(@) , Primary and secondary (but not teritiary amines) form intermolecular hydrogen bonds and thus they boil at highter temperatures than expected. Like ammonia, all amines are basic, although they differ in their basic nature. As amines are considered as derivatives of ammonia, quaternary ammonium salts are considered as derivatives of ammonium salts. Only the quaternary ammonium salts can shown optical activity.
