Q. The reaction of acetaldehyde and HCN, followed by complete acid hydrolysis gives

$C H_{2} = C H - COO H$

$C H_{3} - C H (O H) CON H_{2}$

$C H_{3} C H (O H) COO H$

$C H_{2} = C H CON H_{2}$

$C H_{3} H ∣ C = O + H CN \to C H_{3} CN ∣ C H - O H \to H_{3} O^{+} C H_{3} - CON H_{2} ∣ C H - O H \to H_{3} O^{+} C H_{3} - COO H ∣ C H - O H + N H_{4}^{+}$

Q. The reaction of acetaldehyde and HCN, followed by complete acid hydrolysis gives

CH2​=CH−COOH

CH3​−CH(OH)CONH2​

CH3​CH(OH)COOH

CH2​=CHCONH2​

CH3​H∣C​​=O+HCN→CH3​CN∣CH​​−OH→H3​O+CH3​−CONH2​∣CH−OH​​→H3​O+CH3​−COOH∣CH−OH​​+NH4+​

$C H_{2} = C H - COO H$

$C H_{3} - C H (O H) CON H_{2}$

$C H_{3} C H (O H) COO H$

$C H_{2} = C H CON H_{2}$

$C H_{3} H ∣ C = O + H CN \to C H_{3} CN ∣ C H - O H \to H_{3} O^{+} C H_{3} - CON H_{2} ∣ C H - O H \to H_{3} O^{+} C H_{3} - COO H ∣ C H - O H + N H_{4}^{+}$
