Which of the following statements about hydrogen bonds is false?

Which of the following statements about hydrogen bonds is FALSE? 1. they can only form between two different molecules 2. the donor is a hydrogen atom bonded to a more electronegative atom 3. the more linear the bond, the stronger the attraction 4. the acceptor must contain a non-bonded pair of electrons 5. it is a type of non-covalent bond

Answer

Hydrogen bond is the dipole dipole interaction between electronegative atom like F,O or N and hydrogen atom attach to other electronegative atom like F,O or N. This bond is not a covalent bond, it is a purely dipole-dipole interaction. The more linear the molecule is, the more stronger hydrogen bonding will be there. False statement is 1. because hydrogen bonding are of two types : a) Intermolecular hydrogen bonding – hydrogen bond between two different molecules. b) Intramolecular hydrogen bonding – hydrogen bonding with in the molecule.
