What else can I help you with?
Do hydrogen bonds exist between water molecules?
Yes they do.
What happens to the hydrogen bonds when water is melted?
Nothing. Hydrogen bonds are very strong. When ice is melted, only weak intermolecular forces of attraction that exist between H2O molecules will be broken.
Why isn't Nitrogen very reactive cos?
Nitrogen is usually quite unreactive at both standard pressure and standard temperature. Nitrogen is relatively unreactive because nitrogen molecules are joined together by triple bonds, and these bonds are some of the strongest bonds that can exist between molecules.
Can molecular compounds exist as separate molecules due to covalent bonding?
Yes, molecular compounds are formed through covalent bonding where atoms share electrons to form molecules. These molecules can exist as separate entities due to the strong bonds between the atoms.
What is the importance of chemical bonding in molecules?
Chemical bonds are what keep the atoms in a molecule together, without them you won't exist, the tables and chairs and anything visible would no exist. No compounds would exist but because of the way atoms are held together these bonds exist. It is impossible for them not to make bonds with their current structure.
Are there Substances without covalent bond?
Yes, there are substances that exist without covalent bonds, such as ionic compounds where ions are held together by electrostatic attraction. Metallic bonds are also a type of bond that does not involve sharing of electrons. Additionally, hydrogen bonds, while not true covalent bonds, are intermolecular forces that can exist between molecules.
What is the maximum number of bonds that can exist between two carbons?
No more than 3 bonds (A triple bond) may exist between two carbon atoms.
How do ionic bonds and ionic compounds differ from covenant bonds and molecules?
Ionic bonds is the attracting between opposing forces (positive and negative) while covalent bonds are atoms sharing electrons to get an inert gas configuration (8 electrons in valence shell). Covalent bonds exist as discrete molecules while ionic compounds do not exist as discrete molecules and form large crystal lattices.
Which holds large numbers of different molecules together?
Chemical bonds hold large numbers of different molecules together by forming attractive forces between atoms. These bonds can be covalent, where atoms share electrons, or ionic, where electrons are transferred between atoms to create charged particles that attract each other. These interactions contribute to the stability and structure of molecules and materials.
Which molecules contain the fewest covalent bonds?
Noble gases such as helium, neon, argon, krypton, xenon, and radon contain the fewest covalent bonds because they exist as monatomic molecules, meaning they exist as single atoms rather than bonded pairs of atoms.
What is the strongest force that exist between molecules of ammonia?
The strongest forces that exist between molecules of ammonia (NH₃) are hydrogen bonds. These occur due to the highly electronegative nitrogen atom, which attracts the hydrogen atoms from neighboring ammonia molecules, resulting in a strong interaction. This hydrogen bonding significantly influences ammonia's physical properties, such as its relatively high boiling point compared to other similar-sized molecules.
What is the weak attractive forces which exist between water molecules?
The weak attractive forces between water molecules are called hydrogen bonds. These bonds form between the slightly positively charged hydrogen atoms of one water molecule and the slightly negatively charged oxygen atoms of neighboring water molecules. Hydrogen bonds are responsible for many of water's unique properties, such as high surface tension and cohesion.
