The correct increasing order of extent of hydrolysis is

Options

  1. AC C l 4 < M g C l 2 < A l C l 3 < S i C l 4 < P C l 5
  2. BC C l 4 < A l C l 3 < M g C l 2 < P C l 5 < S i C l 4
  3. CC C l 4 < S i C l 4 < P C l 5 < A l C l 3 < M g C l 2
  4. DC C l 4 < P C l 5 < S i C l 4 < A l C l 3 < M g C l 2

Correct answer

A. C C l 4 < M g C l 2 < A l C l 3 < S i C l 4 < P C l 5

Step-by-step solution

Extent of hydrolysis is proportional to the amount of positive formation charge present on the atomic site prone to attack of H 2 O molecules. C C l 4 < M g C l 2 < A l C l 3 < S i C l 4 < P C l 5
