Q3. Which of the following objects are chiral and which are achiral? a
Sergio039 [100]

Answer:

See explanation

Explanation:

In this question, we have to follow the IUPAC rules. Lets analyze each compound:

a. 1-methylbutane

In this compound we have a chain of 5 carbons, so the correct name is <u>Pentane.</u>

b. 1,1,3-trimethylhexane

In this compound, we longest chain is made of 7 carbons, so, we have to use the name "heptane". Carbon one would be the closet one to the methyl group, so the correct name is  <u>2,4-dimethylheptane.</u>

c. 5-octyne

In this case, carbon 1 would be the closet one to the triplet bond. With this in mind, the correct name is <u>oct-3-yne.</u>

d. 2-ethyl-1-propanol

In this compound, we longest chain is made of 4 carbons, so, we have to use the name "butane". Carbon one would be the carbon with the "OH" group, so the correct name is  <u>2-methylbutan-1-ol.</u>

<u>e. 2.2-dimethyl-3-butanol</u>

In this case, carbon 1 would be the closet one to the "OH". With this in mind, the correct name is <u>3,3-dimethylbutan-2-ol.</u>

See figure 1

I hope it helps!

timama [110]
To be able to calculate the number of moles for this problem, for simplicity, we assume that it is an ideal gas. We use the equation PV = nRT. We do as follows:

PV = nRT
n = PV / RT
n = 1(100000) / 0.08206 (27 + 273.15)
n = 4060.04 mol
