Induced attraction 4. Hydrogen Bonding vanderwaals forces are always present but not very Significant. Hydrogen bonding due to high dipole moment developed due to high electronegativity of 'n compared to H. of NH3 is in areous medlum there will be some ions of Nhat, so yes there will be ponic interactions. There will be depole pnteraction in any polar protic and a poolic med pum po generaliike Hel, acetone, alcohol --etc.
Aldiz is a polar covalent molecule thus the poredominant intermolecular forces would be dipole - dipole forces Maßr and Mgo are Ponic com pocends they the predominant Inter molecular forces would be non-pon Interactione so one og given molecules Nhz exhibit All types of Intermolececar veces forces
