Q:

Order of basicity of amines in gaseous state?

A) 2'> 1'> 3' > NH3	B) 3' > 2' > 1'> NH3
C) 1' > 2' > 3'> NH3	D) 2'> 3'> 1' > NH3

Answer & Explanation Answer: B) 3' > 2' > 1'> NH3

Explanation:

The order of basicity in ammonia is different in gaseous phases vs. aqueous phases due to hydrogen bonding.

So in gaseous phases it's the well known: 3' > 2' > 1'> NH3. Just so we're on the same page, this is due to the inductive effect of electron donating alkyl groups--they destabilize the lone pair on nitrogen atom, making nitrogen more basic.

But in aqueous phase, the order is slightly different: 2'> 1'> 3' > NH3.
