    II>I>III Amines Basicity is 3>2>1>NH3 in gaseous state. But in Aqueous Media There is three factors which determine basicity 1)Inductive Effect 2)Solvation Of Ion 3) Steric Factor For CH3 there is no Steric Factors so Basicity is of Order 2>1>3 For C2H5 and others there is steric hindrance for formation of H-Bonding So it Becomes 2>3>1.
