Scandium (Sc) has the largest atomic mass.
Answer: Sc (Scandium)
Answer:
A<em>=</em><em>4</em>
<em>B</em><em>=</em><em> </em><em>4</em><em>+</em><em>2</em><em> </em><em>=</em><em>6</em>
<em>C</em><em>=</em><em>C</em><em>arbon</em>
<em>D</em><em>=</em><em>10</em>
<em>E</em><em>=</em><em>22</em>
<em>F</em><em>=</em><em>Argon</em><em> </em>
As can be seen in the attached image, α-pyrone has a highly electrophilic carbon atom, since it is attached to two oxygen atoms that are electronegative and subtract electrical charge from the carbon, leaving it with a <u>positive partial charge</u>. By virtue of the above, <u>the bromine atoms, which have an important electron density that makes them good nucleophiles, will be attracted to the aforementioned carbon due to their positive charge</u>, thus favoring the substitution product to a greater extent than that of addition.
