Answer #1

2.so med host HO сор 11 BOSH mad on neto 90 any Dewane atl Ou

1. NaBH4 reduce the ketoen to alcohol

2. Hydrolysis of acetal gives ketome and diol

3. Imine formation by nucleophilic addition

4. Wolff-Kishnner reduction convert ketone to Alkane

5. Wittig reaction gives alkene from carbonyl compounds and phosphorus ylide then hydroysis of acetal givrs back the aldehydes.
