Answer:
3 I'm in college so I know this stuff my guy
Explanation:
sus
Answer:
2Al+Fe2O3-->2Fe+Al2O3
Explanation:
make sure there are the same no. of atoms on each side
Hydrogen Bonding is considered as the strongest Intermolecular Interactions between two protic compounds.
Formation of Hydrogen Bonding:
Hydrogen Bonding takes place between the Hydrogen atom bonded to most electronegative element (i.e. F, O, N) of one molecule and the most electronegative element (i.e. F, O, N) of other molecule. This is because the Hydrogen atom attains a partial positive charge which creates attractive forces with the electronegative atom with partial negative charge.
In given options Hydrogen Bonding can only exist in Methanol (CH₃-O-H). As, the hydrogen atom is directly bonded with Oxygen atom, so it will attain partial positive charge and will interact with the Oxygen atom of second Methanol molecule.
CH₃-O-H - - - - -OHCH₃ ∴ - - - - = Hydrogen Bond
Result:
Methanol (CH₃-OH) <span>exhibits hydrogen bonding as its strongest intermolecular force.</span>
