Identify the structural formula for magnesium hydroxide.

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Mg(OH)2.

  • The correct structural formula for magnesium hydroxide is Mg(OH)₂. This compound consists of one magnesium (Mg) ion and two hydroxide (OH-) ions, held together by ionic bonds.
  • Magnesium has a charge of +2, and each hydroxide ion has a charge of -1, balancing the overall charge to zero. It appears as a white solid and is slightly soluble in water, commonly used as an antacid or laxative.
  • Other options, like MgOH, MgO₂, or Mg₂H₂, are incorrect representations.
