An organic compound (P) has the molecular formula C₈H11NO and can be resolved into enantiomers. (P) does not decolorize bromine water solution. (P) on refluxing with dilute H₂SO₄ yields another resolvable compound Q (C₈H₁₂O₃), which gives effervescence with NaHCO₃. (Q) on treatment with NaBH₄ yields R (C₈H₁₄O₃), which on heating with concentrated H₂SO₄ yields S (C₈H₁₂O₂). Compound (P) on reduction with LiAlH₄, followed by treatment with H₂SO₄, yields the compound shown below:

Let the sum of the degrees of unsaturation in P, Q, R, and S be ; the sum of distinct functional groups in P, Q, R, and S be (if the same functional group appears in two or more compounds, count it only once).

1. Nitrile

2. Carbonyl

3. Carboxylic acid

4. Alcohol

5. Ester

(The amine (–NH) present in P is not counted here, because it is part of a ring system and is not considered a separate functional group in this question’s solution.)
