(i) C5 H10 O must be aldehyde or ketone because it reacts with N H2 OH. (ii) It must be aldehyde as it does not give Fehling test. (iii) It must have CH 2 CO group because it gives iodoform test. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/39c34f3c3207cc101a4088c7f8438290-.png" /> underset(A)C2H10Cl2

Q. A compound $A \to C_{5} H_{10} C l_{2}$ on hydrolysis gives $C_{5} H_{10} O$ which reacts with $N H_{2} O H$ , forms iodoform, but does not give Fehling test. A is:

$C H_{3} - C ∣ Cl H - C ∣ Cl H - C H_{2} - C H_{3}$

(i) $C_{5} H_{10} O$ must be aldehyde or ketone because it reacts with $N H_{2} O H$ .
(ii) It must be aldehyde as it does not give Fehling test.
(iii) It must have $C H_{2} CO$ group because it gives iodoform test.
$(A) C_{2} H_{10} C l_{2}$

Q. A compound A→C5​H10​Cl2​ on hydrolysis gives C5​H10​O which reacts with NH2​OH, forms iodoform, but does not give Fehling test. A is:

CH3​−C∣Cl​H−C∣Cl​H−CH2​−CH3​

(i) C5​H10​O must be aldehyde or ketone because it reacts with NH2​OH. (ii) It must be aldehyde as it does not give Fehling test. (iii) It must have CH2​CO group because it gives iodoform test. (A)C2​H10​Cl2​​

Q. A compound $A \to C_{5} H_{10} C l_{2}$ on hydrolysis gives $C_{5} H_{10} O$ which reacts with $N H_{2} O H$ , forms iodoform, but does not give Fehling test. A is:

$C H_{3} - C ∣ Cl H - C ∣ Cl H - C H_{2} - C H_{3}$

(i) $C_{5} H_{10} O$ must be aldehyde or ketone because it reacts with $N H_{2} O H$ .
(ii) It must be aldehyde as it does not give Fehling test.
(iii) It must have $C H_{2} CO$ group because it gives iodoform test.
$(A) C_{2} H_{10} C l_{2}$
