Predict the ordering of the boiling points of the following?

Question

Predict the ordering of the boiling points of the following:
(i) CH3—O—CH3 (ii) CH3CH2OH (iii) CH3CH2NH2

I need some help figuring this out. Also show the steps taken to get the answer. Thanks

Answer 1

A greater polarity => a higher boiling point.
The methyl-methyl ether should have the lowest.
It's a bit up for grabs if the ethanol or the ethylamine has the higher boiling point. I'll go with the ethanol.

Answer 2

the only one I realize on sight is NaCl - sodium chloride, salt - so I isn't plenty help, now will I? The extra complicated the form, the decrease the boiling factor, i think of, yet what do i be attentive to? The carbon hydrogen complexes - nicely this is all people's wager
