Part A What carboxylic acid would be formed if the malonic ester synthesis (alkylation of diethyl malonate followed by hydrolysis with acidic workup and decarboxylation) were carried out with one equivalent of malonic ester, one equivalent of 1,5-dibromopentane, and two equivalents of hydroxide as the base?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

it would be a gas formation
