For the synthesis of benzoic acid, the only correct combination is:

A(I) (iv) (Q)
B(III) (iv) (R)
C(IV) (ii) (P)
D(II) (i) (S)
Correct Answer

Solution

For the synthesis of benzoic acid, the only CORRECT combination is (II) Acetophenone (i) $${NaOH}/{{Br}_{2}}$$ (S) Haloform

In haloform reaction, methyl ketones are oxidised to the sodium salt of carboxylic acid. The by-product is haloform.

$$\displaystyle Ph-COCH_3 + 3NaOBr \xrightarrow [\Delta ]{{NaOH}/{{Br}_{2}}} Ph-COONa + CHBr_3 +2NaOH$$

Hence, the correct option is $$\text{D}$$
