Which of the following represents the incorrect order of properties?

Options

  1. AN a C l < M g C l 2 < A l C l 3 < S i C l 4 (order of ionic character)
  2. BB e C O 3 < M g C O 3 < C a C O 3 < B a C O 3 (order of thermal stability)
  3. CL i H > N a H > K H > R b H > C s H (order of thermal stability)
  4. DB e S O 4 > M g S O 4 > C a S O 4 > B a S O 4 (Order of solubility in water)

Correct answer

A. N a C l < M g C l 2 < A l C l 3 < S i C l 4 (order of ionic character)

Step-by-step solution

Correct order of ionic character. N a C l > M g C l 2 > A l C l 3 > S i C l 4
