an aqeous soln having 0.5 mole urea has elevation in boiling point of 4 degrees...what would be the elevation in boiling point pf an aqeous soln containing 0.5 mole methyl amine....

i am confused on whether to consider primary amine as a base and water as a lewis acid or take abnormality due to  h bonding into consideration..

in case of consideration of acid base reacn being considered delta t b would be 8 degress because the particles would be doubled because of the production of  RNH3+ AND  OH- . WHILE IF H BONDING IS CONSIDERED DELTA TB WOULD BE 2 DEGREES.

KINDLY HELP
