✓

Answer

When treated with Tollen's reagent, But-2-enal produced in the above reaction produces but-2-enoicacid.$\text{CH}_3-\text{CH}=\text{CH}-\text{CHO}\xrightarrow[\text{Tollen's}\text{ reagent}]{\big[\text{Ag}(\text{NH}_3)_2\big]^+\text{OH}^-}\text{CH}_3\text{CH}=\text{CHCOOH}\\\text{But - 2 - enal}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{But - 2 - enoic acid}$
