1. A as CH3OH has hydrogen atom attached to highly electronegative atom, Oxygen. Note: For Hydrogen bond to occur, Hydrogen must be attached to F(Flourine), O(Oxygen) and N(Nitrogen)
2. D as ice exhibits covalent bond as a single compound and exhibits hydrogen bond between molecules.
3.C as Hydrogen atom is attached to Oxygen atom.
