Question

Assertion: Toluene in presence of UV rays forms benzaldehyde.
Reason: Dichlorotoluene is formed as an intermediate.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

Oxidation of toluene using $Cr{O}_3$ in acetic anhydride or $Cr{O}_{2}C{l}_2$ in $CC{l}_4$ or $C{S}_2$ and then hydrolysis gives benzaldehyde. No such intermediate is formed.
