Homework Answers
(a) Generally aqueous base removes H2 gas from substrate. In substrate firstly base removes most acidic proton which further H2 gas evolved.
(b) Here again base removes most acidic proton. Further 3 membered cyclic lactone formation favoured.

draw the mechanism as well please! with lone pairs
Question 8 When the following ketone is treated with aqueous sodium hydroxide, the aldol product is obtained in poor yields. In these cases, special distillation techniques are used to increase the yield of aldol product. Predict the aldol addition product that is obtained, and propose a mechanism for its formation. For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer. Do not draw out...
