Options

  1. AThree numbers are in an increasing geometric progression with common ratio r . If the middle number is doubled, then
  2. BThree numbers are in an increasing geometric progression with common ratio r . If the middle number is doubled, then
  3. CThree numbers are in an increasing geometric progression with common ratio r . If the middle number is doubled, then
  4. DThree numbers are in an increasing geometric progression with common ratio r . If the middle number is doubled, then

Correct answer

D. Three numbers are in an increasing geometric progression with common ratio r . If the middle number is doubled, then

Step-by-step solution

Aromatic nucleophilic substitution reaction takes place via the formation of a carbanion intermediate. Hence, the rate of reaction depends on the stability of the carbanion.

Electron withdrawing effect can stabilise the carbanion. The Electron withdrawing nature of the nitro group will be minimum at the meta position.

Hence the correct answer is

The compound which will have the lowest rate towards nucleophilic aromatic substitution on treatment with OH ^ – is
