Question

28 multiple choice 2 points what intermolecular forces is present in methylamine molecule, ch₃nh₂? hydrogen bonding only both london dispersion forces and dipole-dipole forces both london dispersion forces and hydrogen bonding london forces only

Explanation:

Methylamine ($\ce{CH3NH2}$) has London dispersion forces (present in all molecules) and hydrogen bonding (due to $\ce{N - H}$ bonds, as N is electronegative and H is bonded to it). It also has dipole - dipole, but the option with both London and H - bonding is correct as H - bonding is a special dipole - dipole, and the option "both London dispersion forces and hydrogen bonding" includes the key forces.

Answer:

C. both London dispersion forces and hydrogen bonding
