Answer:
We will have zero bonds
Explanation:
In this case, we have to start with the <u>structure of 4,5-diethyloctane</u>. This name ends with the <u>suffix "ane"</u> therefore we have an <u>alkane</u>. All the alkanes are made with <u>single bonds</u> between carbons and <u>single bonds</u> between carbon and hydrogen.
The molecule will have a <u>carbon chain of eight carbons</u> and we will have 2 <u>branches</u>, one ethyl on carbon 4 and another ethyl on carbon 5. (see figure 1)
