Q5 / 180 · KCET 2023 · Chemistry

Which of the following is an organometallic compound?

  • A
    $\mathrm{CH}_3 \mathrm{COONa}$
  • Correct answer
    B
    $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{MgBr}$
  • C
    $\left(\mathrm{CH}_3 \mathrm{COO}\right)_2 \mathrm{Ca}$
  • D
    $\mathrm{CH}_3 \mathrm{ONa}$

Solution

$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{MgBr}$ is considered as an organometallic compound because it contains a direct bond between a carbon atom and a metal atom (magnesium). Organometallic compounds contains at least one carbon-metal bond. They can participate in variety of reactions and often used as reagents or catalysts in organic synthesis.

Hence, the correct answer is option: 'B'.
