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 Pentane.

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 2,4-dimethylheptane.

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 oct-3-yne.

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 2-methylbutan-1-ol.

e. 2.2-dimethyl-3-butanol

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

See figure 1

I hope it helps!

A chemist uses a standard solution of 0.210 M lithium hydroxide (LiOH) to titrate 28.10 mL of sulfurous acid acid (H2SO3), she f

erik [133]

Answer:

0.0827M of H₂SO₃

Explanation:

LiOH reacts with H₂SO₃ to produce water and Li₂SO₃, thus:

2LiOH + H₂SO₃ → 2H₂O + Li₂SO₃

Where 2 moles of lithium hydroxide react with 1 mole of sulfurous acid.

As the chemist requires 22.14mL = 0.02214L of a 0.210M solution to neutralize the acid, moles of LiOH are:

0.02214L × (0.210mol / L) =0.004649 moles of LiOH.

As 2 moles of LiOH react with 1 mole of H₂SO₃, moles of H₂SO₃ are:

0.004649 moles of LiOH ₓ (1 mole H₂SO₃ / 2 mol LiOH) =

0.002325 moles of H₂SO₃

These moles are present in 28.10mL = 0.02810L. Thus, molar concentration of the acid is:

0.002325 moles H₂SO₃ / 0.02810L = 0.0827M of H₂SO₃
