The structure of the alkyl bromides used in a malonic ester synthesis of ethyl 2-methyl-4-pentenoate are as drawn in the attached image.
<h3>Ethyl 2-methyl-4-pentenoate by Malonic ester synthesis.</h3>The malonic ester synthesis is a chemical reaction characterized by the alkylation of diethyl malonate or a similar ester of malonic acid at the carbon alpha (directly adjacent) to both carbonyl groups, and subsequently converted to a substituted acetic acid.
Hence, it follows from the structure of Ethyl 2-methyl-4-pentenoate that the alkyl bromides used are Ethyl bromide and methyl bromide.

<h3>What is alkyl bromide?</h3>
When halogens such as Br, Cl, I, attched to the sp3 carbon atom of alkyl group, they called alkyl halides.
Here, bromide is attached to an alkyl group.
Ethyl bromide and methyl bromide are the alkyl halides used in synthesis of ethyl 2-methyl-4-pentenoate
Thus, ethyl bromide and methyl bromide are the alkyl bromides.

Electronic configuration
So, there are 5 unpaired electrons present in group 7A(17).
<h3>What are Unpaired Electrons?</h3>- An unpaired electron is an electron that doesn't form part of an electron pair when it occupies an atom's orbital in chemistry.
- Each of an atom's three atomic orbitals, designated by the quantum numbers n, l, and m, has the capacity to hold a pair of two electrons with opposing spins.
- Unpaired electrons are extremely uncommon in chemistry because an object carrying an unpaired electron is typically quite reactive. This is because the production of electron pairs, whether in the form of a chemical bond or as a lone pair, is frequently energetically advantageous.
- They play a crucial role in describing reaction pathways even though they normally only appear momentarily during a reaction on a thing called a radical in organic chemistry.
