Choose the correct option(s) for the following set of reactions
Options:(select one or more)
Answer:
A, B, D
Solution:
Starting compound reacts with ethylene glycol + dry HCl → acetal (Q) formation (carbonyl protection).
Q with (Ph)₃P gives phosphonium salt (R), which on treatment with base (C₆H₅Li) forms ylide (S).
Ylide undergoes Wittig reaction with cyclohexanone → alkene product (T).
T on hydrolysis (H⁺) regenerates carbonyl compound (U).
U gives yellow ppt with I₂/NaOH (haloform test) → confirms presence of –COCH₃ group.
Hence, correct options matching all steps are: A, B, D
