    yes shweta it will give positive fehling test. Alliphatic aldehyde gives positive test...here in your question aldehyde is not aromatic as it is not directly attached to benzene ring..so it is alliphatic aldehyde and gives positive test

    1. Fehling’a Solution test Fehling's solution= Fehling A (aq CuSO4) + Fehling B (sodium potassium tartrate) + NaOH Aldehyde gives +ve test and red color of Cu2O is observed. ( Benzaldehyde do not give Fehling's as well as Benedict soln test because these are weak oxidising agent compared to Tollen's) 2. Benedict's solution test Benedict's solution= aq CuSO4 + sodium potassium citrate + NaOH This test is given by all reducing sugar and aldehyde except benzaldehyde. +Ve test gives red color of Cu2O ppt.
