Question 22

Match the molecule or compound to the type of bond found between the elements.

Column A
1.
NaCl:
NaCl
2.
MgBr2

:
MgBr2

3.
CO2

:
CO2

4.
SO2

:
SO2

Column B
a.covalent bond
b.ionic bond

1 answer

To match the molecules and compounds from Column A with the appropriate type of bond from Column B:

  1. NaCl: This compound is formed between sodium (Na) and chlorine (Cl) and involves the transfer of electrons from Na to Cl, resulting in an ionic bond.
    Match: NaCl - b. ionic bond

  2. MgBr2: This compound consists of magnesium (Mg) and bromine (Br). Magnesium transfers electrons to bromine, creating an ionic bond.
    Match: MgBr2 - b. ionic bond

  3. CO2: This molecule is formed between carbon (C) and oxygen (O) through the sharing of electrons, which results in a covalent bond.
    Match: CO2 - a. covalent bond

  4. SO2: This molecule is made up of sulfur (S) and oxygen (O), also formed through the sharing of electrons, leading to a covalent bond.
    Match: SO2 - a. covalent bond

Summary of Matches:

  • NaCl - b. ionic bond
  • MgBr2 - b. ionic bond
  • CO2 - a. covalent bond
  • SO2 - a. covalent bond
