Identify the correct reagent(s) to distinguish between pairs of compounds given

Options

A. proponal & propanone can be distinguished by using `I_2 & NaOH`
B. Benzaldehyde and acetophenone `(C_6 H_5 COCH_3)` can be distinguished with Tollen's reagent
C.
D. Formaldehyde and acetaldehyde can be distinguished by using `I_2 & NaOH`

Answer

A, B, C, D

Explanation

`CH_3 -CH_2 - overset(O) overset(||)C-H underset(NaOH) overset(I_2)to ` NO reaction
` CH_3 - overset(O ) overset(||) C-CH_3 underset(NaOH) overset(I_2)to CHCI_3 +CH_3 - overset(O ) overset(||)C-O Na` can be distinguished by ` I_2 //NaOH `

`(d ) H- overset(O ) overset(||)C -H underset(NaOH) overset(I_2) to `No reaction` CH_3 - overset(O) overset(||)C-H underset(NaOH) overset(I_2) to CHI_3 CH_3 - overset(O) overset(||)C-O Na`
