Chemistry Objective question answer - Ethers, Amines and Nitriles

 

Find the correct answer by clicking on the choice given.

1. The reason that CH3NH2 is a stronger base than CH3OH is due to the fact that...

(a) hyperconjugation resonance of the product, CH3NH3+, is better than for CH3OH2+.

(b) resonance of the product, CH3NH3+, is better than for CH3OH2+.

(c) the electronegativity of nitrogen is less than oxygen, thus making the electron pair more available.

(d) It isn't. The oxygen atom has 2 non-bonded pairs of electrons making it twice as basic.
