(a)
Interpretation:
Type of bonding in AlCl3 and its chemical name needs to be determined. Also, whether it can conduct electricity or not need to be determined.
Concept introduction:
There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond.
- Ionic bond
- Molecular covalent bond
- Metallic bond
- Network covalent bond

Answer to Problem 9RE
AlCl3 - ionic bond, aluminium chloride, it will conduct electricity when dissolved in water.
Explanation of Solution
AlCl3 is an ionic compound as it contains a metal and a nonmetal. It is called aluminium chloride. It has ionic bond between aluminium and chlorine atoms. The valence electrons are transferred from one metal atom to nonmetal atoms. It can conduct electricity when dissolved in water as the metal and nonmetal ions are free to move in solution.
(b)
Interpretation:
Type of bonding in O2 and its chemical name needs to be determined. Also, whether it can conduct electricity or not need to be determined.
Concept introduction:
There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond. Chemical bonds hold the atoms together. There are four types of bonds:
- Ionic bond
- Molecular covalent bond
- Metallic bond
- Network covalent bond

Answer to Problem 9RE
O2 - molecular covalent bond, oxygen, it will not conduct electricity
Explanation of Solution
Oxygen gas is made of only oxygen atoms. Here, oxygen is a nonmetal. In O2 molecule, the valence electrons are shared between two oxygen atoms. The bonding between two oxygen atoms is molecular covalent. Here the nucleus of one atom is attracted to valence electrons of another atom. It cannot conduct electricity because it does not contain any free electron or ion.
(c)
Interpretation:
Type of bonding in AgOH and its chemical name needs to be determined. Also, whether it can conduct electricity or not need to be determined.
Concept introduction:
There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond. Chemical bonds hold the atoms together. There are four types of bonds:
- Ionic bond
- Molecular covalent bond
- Metallic bond
- Network covalent bond

Answer to Problem 9RE
AgOH - ionic bond, silver hydroxide, it will conduct electricity when dissolved in water.
Explanation of Solution
AgOH is an ionic compound as it contains a metal and a nonmetal. It is called silver hydroxide. It has ionic bond between silver ion and hydroxyl ion. The valence electrons are transferred from one metal atom to nonmetal atoms. It can conduct electricity when dissolved in water as the metal and nonmetal ions are free to move in aqueous solution.
(c)
Interpretation:
Type of bonding in Pt and its chemical name needs to be determined. Also, whether it can conduct electricity or not need to be determined.
Concept introduction:
There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond. Chemical bonds hold the atoms together. There are four types of bonds:
- Ionic bond
- Molecular covalent bond
- Metallic bond
- Network covalent bond
(c)

Answer to Problem 9RE
Pt- metallic bond, platinum, it will conduct electricity.
Explanation of Solution
Platinum has metallic bond as it is made of metal atoms. The atoms are bonded by the attraction between the positively charged nucleus of one atom and negatively charged electrons around the nucleus of other atom. The valence electrons are free to move so it can conduct electricity.

- Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds.
