Web13 aug. 2024 · Intermolecular attractions are attractions between one molecule and a neighbouring molecule. The forces of attraction which hold an individual molecule together (for example, the covalent bonds) are known as intramolecular attractions. These two words are so confusingly similar that it is safer to abandon one of them and never use it. Web14 apr. 2024 · Hydrogen-bonded complexes are formed between two chain lengths of 4-alkoxystilbazoles and six different chlorophenols. Single crystal structure determinations were possible for four of the complexes, all of which showed a similar dimeric motif in which two chlorophenols formed a loose back-to-back dimer with a stilbazole hydrogen … WebWater is made of hydrogen and oxygen—it's called H 2 O because every molecule of water has two hydrogen atoms (H 2) and an oxygen atom (O). When you wet your hair, water molecules sneak in between the proteins of the cortex and join these hydrogen bonds. Your hair swells up, absorbing up to 30 percent of its weight in water. daily mirror racing pages today
