Final answer:
The nature of bonding between N,N-dichloromethylamine and water is hydrogen bonding. This occurs due to the N-H bonds in N,N-dichloromethylamine, which can attract the hydrogen atoms of water molecules. Hydrogen bonding is significant for the solubility of substances in water and is responsible for the unique properties of ice.
Step-by-step explanation:
Nature of Bonding Between N,N-Dichloromethylamine and Water
The nature of bonding between N,N-dichloromethylamine and water is primarily hydrogen bonding. Hydrogen bonds are a type of intermolecular force that occurs when a hydrogen atom, which is covalently bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine, attracts another electronegative atom. In the case of N,N-dichloromethylamine, the nitrogen atom can form a hydrogen bond with the hydrogen atoms of water molecules because it contains N-H bonds which are required for hydrogen bonding.
Hydrogen bonding is relatively weaker than covalent or ionic bonds, but it is stronger than Van der Waals forces. The ability for a substance to form hydrogen bonds with water enhances its water solubility. For instance, amines like N,N-dichloromethylamine are more water-soluble compared to alkanes because they can engage in hydrogen bonding with water.
The shape of the water molecule, with its bent geometry and polar O-H bonds, allows it to form a tetrahedral network of hydrogen bonds, which is responsible for the unique properties of ice. In ice, each water molecule is hydrogen bonded to four others, leading to an expanded structure and lower density compared to liquid water.
