If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of these choices shows a hydrogen bond?
-O, H-C-
-N, H-O-
-C, H-F-
H-H

Respuesta :

taskmasters
The correct answer among the choices listed above is the second option. The compound -N...H-O- would show a hydrogen bond. Hydrogen bond is present between the hydrogen atom and the nitrogen atom. It is the a result of the electromagnetic attraction between a hydrogen atom and a electronegative element.

- N ... H - O -

Further explanation

Given:

A solid line represents a covalent bond and a dotted line represents intermolecular attraction.

The Question:

Which of these choices shows a hydrogen bond?

Solution:

Hydrogen bonds are mainly formed as OH–N. About 70% of the hydroxyl (-OH) groups participate in hydrogen bonds, and about 70% of the acceptors are nitrogen atoms.

- - - - - - - - - -

Notes:

  • Hydrogen bonds are intermolecular attractions that are very polar and contain hydrogen atoms.
  • Hydrogen bonding is caused by the attraction between hydrogen atoms from one molecule to another atom which is very electronegative, namely F, O, and N.
  • Substances that have hydrogen bonds require more energy to break them. Therefore, the boiling point and the melting point are very high.
  • Examples of compounds with intermolecular forces in the form of hydrogen bonds are HF, NH₃, and H₂O.
