when reporting calculations from sig figs, report the number of sig figs in the least accurate measurement

alexdok [17]

Answer:

See figure 1

Explanation:

In this question, we have to remember that each <u>carbon has 4 electrons</u> and each <u>hydrogen has 1 electron</u>. Additionally, the structure proposed have to have <u>8 electrons for each atom</u> <u>(except hydrogen)</u>. With this in mind, we need to have a <u>double bond</u> between the carbons, because in this arrangement each carbon would have 8 electrons <u>(octet rule)</u>.

See figure 1

I hope it helps!
