5-Ethyl-3,3,4-trimethylheptane has 3 secondary carbon. A primary carbon written as 1° is a carbon that has one carbon atom attached to it. A secondary carbon written as 2° is a carbon attached to two other carbons, while a tertiary carbon written as 3° is a carbon attached to three other carbons.

Answer:

3 secondary carbons are found in 5-ethyl-3,3,4-trimethylheptane.

Explanation:

5-ethyl-3,3,4-trimethylheptane's structure can be seen in the attached picture, in this structure, each vertex represents one carbon atom.

<em>A secondary carbon</em> is a carbon that is bonded to only 2 other carbon atoms, each secondary carbon is highlighted in blue in the attached picture.

I'm so sorry I took long, I'm answering answer after answer :)
Not sure if this is helpful :)
I know these are things in order for an animal to be endangered, but just pick answer that's not these I guess? "Which of the following"

A sample of pure lithium carbonate contains 18.8% lithium by mass. What is the % lithium by mass in a sample of pure lithium car

VashaNatasha [74]

Answer:

There is 18.8% lithium by mass in second sample

Explanation:

Both the two samples are pure lithium carbonate. So % lithium by mass will be same in both samples. This can be proved mathematically as follows-

Let's assume weight of first sample is x g

So, 100 g of sample contains 18.8 g of lithium

Hence, x g of sample contains $(\frac{18.8}{100}\times x)$ g of lithium

Now, the second sample has weight equal to 2x g

So, 2x g of sample contains $(\frac{18.8}{100}\times 2x)$ g of lithium

So, % lithium by mass in second sample = $(\frac{\frac{18.8}{100}\times 2x}{2x})\times 100$ % = 18.8%
