Assertion (A): A high saponification value indicates fatty acids of short chain length.
Reason (R): More moles of alkali are needed per gram when the molecules are smaller.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the inverse relation: coconut oil with its short chains has a high value while a long chain oil such as rapeseed has a considerably lower one. The relation is inverse rather than direct.
