Question

Which of the following bond types is generally the weakest? Covalent logic Metallic Hydrogen Van der Waals bonding is responsible for binding hydrogen and oxygen atoms together in a water molecule Covalent Logic Metallic Hydrogen Van der Waals bonding is responsible for binding carbon atoms together within one grapheme sheet Covalent Logic Metallic Hydrogen Van der Waals Which type of bonding is associated with solid materials comprised of charged constituents held together electrostatic forces? Covalent Ionic Metallic Hydrogen Van der Waals Which of the following systems is not expected to feature bonds between atoms whose valence orbital's are sp^3 hybridized? Silicon Germanium NaCI Carbon (Diamond) Si-Ge Solid Solution The most commonly produced structural form of metals can be described as: Non-crystalline Single Crystal Textured Polycrystalline Glass Random Polyesters Identify the valid unit cell that conveys the highest symmetry of the following 2-D lactic

Explanation / Answer

1)
Vander waals force is weakest as it depends only the mass
Answer: e

2)
H and O in H2O forms covalent bond because this bond is formed by sharing electrons between hydrogen and oxygen
Answer: a

3)
It is covalent same as we discussed above
Answer: a

4)
Electrostatic force is there between ionic bonds
Answer: b
