Chemistry · Aldehyde and Ketones: Nature of carbonyl group, nucleophilic addition to >C=O group, relative reactivities of aldehydes and ketones

Assertion (A): Aldehydes are one of the constituents of photochemical Reason (R)

Assertion (A): Aldehydes are one of the constituents of photochemical \( \operatorname{sinog} \) Reason (R): Aldehydes are produced by photochemical oxidation of hydrocarbons by ozone.

  • A. Both A and R are true and R is the correct explanation of A.
  • B. Both A and R are true but R is not correct explanation of A.
  • C. A is true and \( \mathrm{R} \) is false
  • D. A is false and R is true

Step-by-step solution

Aldehydes are indeed constituents of photochemical smog. They are formed through the photochemical oxidation of hydrocarbons by ozone, which occurs under sunlight. Thus, the reason correctly explains how aldehydes become part of photochemical smog.
