3-hydroxybutanal formed when X reacts whith Y in dilute Z solution. What are X, Y, and Z?A. `X = CH_(3)CHO, Y = (CH_(3))_(2)CO, Z = NaOH`B. `X = CH_(3)CHO, Y = CH_(3)CHO, Z = NaCI`C. `X = (CH_(3))_(2)CO, Y = (CH_(3))_(2)CO, Z = HCI`D. `X = CH_(3)CHO, Y = CH_(3)CHO, Z = NaOH` |

Answer» Correct Answer - D The product obtained is `CH_(3)-underset(OH)underset(|)(CHCH_(2)CHO` This product is obtained when `2`molecules of `CH_(3)CHO` are heated with concentrated alkali `(NaOH)` `CH_(3)underset(X)(CHO)+underset(Y)(CH_(3))CHOoverset(NaOH)underset(Z)to` `CH_(3)underset(OH)underset(|)CH-CH_(2)-CHO` The aldehydes having `alpha`-hydrogen atom on heating with concentrated alkali give brown mass, aldol condensation. |
