Answer»

`UNDERSET(OH)underset(|)(CH_(2))-underset(OH)underset(|)(CH)-underset(OH)underset(|)(CH)-CH=CH-underset(OH)underset(|)(CH)-underset(OH)underset(|)(CH)-underset(OH)underset(|)(CH_(2)`)`

`underset(OH)underset(|)(CH_(2))-underset(OH)underset(|)(CH)-underset(OH)underset(|)(CH)-CH=CH-underset(OH)underset(|)(CH)-underset(OH)underset(|)(CH)-CH=O`
`HOOC-CH_(2)-underset(OH)underset(|)(CH)-CH=CH-underset(OH)underset(|)(CH)-CH_(2)-COOH`

Solution :Carbohydrates (`alpha`-hydroxy carbonyl) gives positive TEST with molish reagent.
