MCQ
Non-polar solvent is
  • A
    Dimethyl sulphoxide
  • ✓
    Carbon tetrachloride
  • C
    Ammonia
  • D
    Ethyl alcohol
✓

Answer

Correct option: B.
Carbon tetrachloride
b
Due to its symmetrical structure, carbon tetrachloride $\left( CCl _4\right)$ is non - polar. Its non-polar nature makes it a suitable solvent for dissolving non-polar compounds. Carbon tetrachloride is convenient as a solvent for $NMR$ because it contains no protons, however, its poor dissolving power limits its usefulness.
