Solution and Explanation
(i) On treatment with dilute alkali, ethanal produces 3-hydroxybutanal gives butane-1, 3-diol on reduction.
(ii) On treatment with dilute alkali, ethanal gives 3-hydroxybutanal which on heating produces but-2-enal.
(iii) When treated with Tollen's reagent, But-2-enal produced in the above reaction produces but-2-enoic acid
