(c) phenyl acetic acid (d) benzoic acid

Answer 1

Answer:

C₆H₅CH₃ □(→┴CrO₂Cl₂) Z

In the given sequence Z is:

(a) benzaldehyde

(b) toluic acid

(c) phenyl acetic acid ✔✔

d) benzoic acid

Answer 2

Option (a)

benzaldehyde

Explanation:

C₆H₅CH₃ is Toluene.

Uses of C₆H₅CH₃:

• Toluene is used to thinner in paints and varnishes. This reduced the density.
• It is also used as a remover.
• Toluene is also used in glue.

CrO₂Cl₂( Chromyl chloride) is used in organic oxidation.

C₆H₅CH₃+CrO₂Cl₂→ C₆H₅CHCr₂O₄Cl₂+2HCl.

Since C₆H₅CHCr₂O₄Cl₂ is so unstable.

It will break again and form C₆H₅CHO (benzaldehyde)

$C_6H_5CH_3\xrightarrow[] {CrO_2Cl_2} C_6H_5CHO$

(Toluene)                 (benzaldehyde)
