Solution and Explanation
It is given that the compound(with molecular formula \(C_9H_{10}O\))forms 2,4-DNP derivative and reduces Tollen's reagent.Therefore,the given compound must be an aldehyde.
Again,the compound undergoes cannizzaro reaction and on oxidation gives \(1,2-benzenedicarboxylic\) acid.Therefore,the\( -CHO\) group is directly attached to a benzene ring and this benzaldehyde is ortho-substituted.Hence,the compound is \(2-ethylbenzaldehyde.\)
The given reactions can be explained by the following equations.

Questions Asked in CBSE CLASS XII exam
A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
