Options

  1. ACaX2{CaX}_{2}
  2. BMgX2{MgX}_{2}
  3. CSrX2{SrX}_{2}
  4. DBeX2{BeX}_{2}

Correct answer

D. BeX2{BeX}_{2}

Step-by-step solution

Beryllium Halides are more covalent in nature, this is due to small size and high charge density of Be+2B{e}^{+ 2} ion. Hence it has high polarization power and more covalent character.
