Explanation / Answer

N(CH3)3

is nonpolar, it is trigonal planar, center atom is N, CH3 is bonded to N in each case

since this is nonpolar, expect only:

inducedp dipole - induced dipole (london dispercion forces)

B)

COH2 --> HCOOH formic acid,

it will be polar, and H-bond present

choose

Hydrogen bonding

Dipole- Dipole forces

c)

H2O --> simlarly, has OH group and it is polar

Hydrogen bonding

Dipole- Dipole forces
