CBSE Class 12 · 2016 · Delhi · Aldehydes Ketones and Carboxylic AcidsLong Answer

WhatsApp Email
(a) Write the structures of A, B, C and D in the sequence shown in the figure (Delhi 2016).
Structure Sequence for A–D
Sequence for A–D

Answer: Follow the printed sequence: each reagent arrow fixes the next letter by its standard transformation.

Solution

Work the displayed chain left to right: the printed reagent on each arrow (hydrolysis, reduction, oxidation, named reaction) converts the previous structure into the next — write A, B, C, D at those stages, carrying the rest of the skeleton unchanged.
