Write the iupac name for the compound below. be sure to use correct punctuation.
1 answer:
I can't answer this question if the structural formula is not given. However, I found a similar problem in terms of wording. Taking this problem to be solved, let's take a look at the structural formula as shown in the second picture. First, you must know the parent chain, which is the longest chain. This is a trial-and-error process. The longest chain which has a branching group that is nearest to the head is the correct numbering. In this case, the longest chain has 8 carbon atoms. Thus, the base of the name if octane. Because a 3-carbon chain is branching from the 4th carbon, the IUPAC name of the compound shown is: <em>4-propyloctane.</em>

Explanation:
Titration is a method used to determine the concentration of a substance. The formula for this is:
Where M is the molarity of the acid or base and V is the volume of the acid or base.
We know that 46.0 milliliters of a 0.15 molar solution of nitric acid wereused in the titration. 25.0 milliliters of solution of calcium hydroxide of unknown molarity were also used.
Substitute these known values into the formula.
We are solving for the molarity of the base, so we must isolate the variable . It is being multiplied by 25.0 milliliters. The inverse operation of multiplication is division, so we divide both sides of the equation by 25.0 mL.
The units of milliliters (mL) cancel.
The original measurements have 2 or 3 significant figures. We always round our answer to the least number of sig figs, which is 2. For the number we calculated, that is the hundredths place. The 6 in the thousandths place tells us to round the 7 up to an 8.
The concentration of calcium hydroxide is approximately <u>0.28 M.</u>
