Which of the following molecules has hydrogen bonding as its only intermolecular force? (a) C_3H_7OH (b) H_2O (c) HOCH_2CH_2OH (d) NH_3 (f) None, all of the above exhibit dispersion forces. Which of the following molecules can form hydrogen bonds...
In ice, the crystalline lattice is dominated by a regular array of hydrogen bonds which space the water molecules farther apart than they are in liquid water. This accounts for water's decrease in density upon freezing. In other words, the presence of hydrogen bonds enables ice to float, ...
But while it’s present in nearly all molecules in living things, it’s very scarce as a gas – less than one part per million by volume. Hydrogen can be produced from a variety of resources, such as natural gas, nuclear power, biogas and renewable power like solar and wind. The ...
What do the polarity and shape of water molecules have to do with their ability to form hydrogen bonds?Hydrogen BondingThis is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X-H in which...
Atoms can combine in many different ways as molecules. The same atoms may combine in different proportions to form different molecules. As an example, two hydrogen atoms and one oxygen atom form water (H2O), while two hydrogen atoms and two oxygen atoms form hydrogen peroxide (H2O2). It is...
2-Butene-1,4-diol, also known as 2-Butene-1,4-diol, is a colorless liquid at room temperature and pressure. It is soluble in water and most organic solvents. This polar molecule can form hydrogen bonds with water molecules due to the presence of two hydroxyl functional groups. It finds...
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond. An overall chemical reaction that breaks bonds and forms new ones can be endothermic...
Being entirely made of hydrogen and carbon, organic molecules fall under the broad category of hydrocarbons, which includes a wide range of other types of molecules. All hydrocarbons are comprised of around one oxygen atom in their composition, but they can be made up of any arrangement of atom...
The intermolecular forces of attraction (IMFA) are the interactions occurring between molecules. These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling poi...
Molecules form when atoms bond with each other. They either form covalent bonds, in which the atoms join by sharing electrons with each other, or ionic bonds, in which neutrally charged atoms lose electrons, and bond with other atoms to restore balance. The noble gases are outliers because ...
