1) The third carbon became enolate in the ring formation of product A
2) The right carbonyl carbon( position 8) was attacked in the ring formation of product A
3)The carbon at 7th position became enolate in the ring formation of product .
4) The left carbonyl carbon (position 2) was attacked in the ring formation of product B.
Iam little confused about the structure of product A. And the actual product is given below.

Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...
