Vedclass · Answer

(A) Fehling's test is given by aliphatic aldehydes only.$1$. Benzaldehyde: Aromatic aldehyde (Negative)$2$. Acetaldehyde $(CH_3CHO)$: Aliphatic aldehyde (Positive)$3$. Acetone: Ketone (Negative)$4$. Acetophenone: Aromatic ketone (Negative)$5$. Methanal $(HCHO)$: Aliphatic aldehyde (Positive)$6$. $4$-nitrobenzaldehyde: Aromatic aldehyde (Negative)$7$. Cyclohexanecarbaldehyde: Aliphatic aldehyde (Positive)Thus,the compounds that give a positive Fehling's test are Acetaldehyde,Methanal,and Cyclohexanecarbaldehyde.The total number of such compounds is $3$.

From the compounds given below,the number of compounds which give a positive Fehling's test is:
Benzaldehyde,Acetaldehyde,Acetone,Acetophenone,Methanal,$4$-nitrobenzaldehyde,cyclohexane carbaldehyde.
