Answer 1

1. 
   All of the compounds mentioned below are &-B unsaturated Carbonge compounds of can be prepared by Aldof condensatton Reaction . SH= Starting Material @ Czetz enfçcu 2 they cho self condensation So, the above molecule can be prepared by of propanal. an 24 etcurean 2 cucuz so, the above molecule can be prepared by self condensation - Acetone. ③ pung e n - 2 en dry (SM) so the above molecule can be prepared by self condensatic of terophenone, o ang an & not ou confon-e-enfon the 2 Boot eno & cucu so, the above molecule can be prepared by the Reaction of 2 molecule of p-methoxy benzaldehydet Peltone.
   
   0,20 <e gar a ntant i Br =), no te jete (SM-1) (SM-2) so the above compound can be prepared by the reaction of SM-L A SM-2. 240 a tentou-se u cho t not NOL (SM-1) (SM-2) prepared by the reaction of so the above molecule can be SH-1 & SM-2.
