• B. Ortho , meta , para
• C. Para , ortho , meta
• D. Meta , ortho , para

Answer 1

Answer: (A)

Para , meta , ortho

Steric hindrance is the stopping of a chemical reaction which might be caused by a molecule's structure.

From the image we can see that para-cresol has least steric hindrance and ortho-cresol has most steric hinderance.
