is this wt u need ??
A. Iron is the best insulater
Oxygen, Nitrogen and Fluorine
Explanation:
In order to participate in a hydrogen bond, a hydrogen atom must be covalently bonded to one of the oxygen, nitrogen and fluorine.
- Hydrogen bonding is a type of dipole - dipole attraction between two specie.
- It is an intermolecular force of attraction.
- This bond type forms when hydrogen is bonded to a more electronegative atom.
- These atoms are oxygen, nitrogen and fluorine
- These species draws the electron shared more to themselves and leaves a partial positive charge on the hydrogen and a negative charge on them.
- The electrostatic force of attraction between the hydrogen of one molecule and the O/N/F of another molecule cause the formation of hydrogen bonds.
