Hydrogenation (H2/Pd-C) of 3,4-dimethyl-3-hexene (3,4-dimethyl hex-3-ene) would be expected to form A) an enantiomeric pair for

both the (E) and (Z) isomers. B) an enantiomeric pair for the (E) isomer and one meso compound for the (Z) isomer. C) one meso compound for the (E) isomer and an enantiomeric pair for the (Z) isomer. D) will not form any stereoisomers since the product is a saturated hydrocarbon. E) None of the above provide a correct response.

Answer:

D) will not form any stereoisomers since the product is a saturated hydrocarbon.

Explanation:

Stereoisomerism, or spatial isomerism,refers to a type of isomerism in which  two or more molecules have the same molecular formula and atom to atom connectivity but different three-dimensional orientations of those atoms in space.

Stereoisomerism occurs in alkenes because free rotation about the C=C bond is hindered. Thus, the molecule is "locked" in a particular orientation. In a saturated alkane, there is unrestricted free rotation about the C-C bond hence straight chain alkanes do not have steroisomers.

The product formed is 3,4-dimethyl hexane which is a straight chain saturated alkane. This compound does not exhibit stereoisomerism.

kherson [118]

The correct answer is 0.44ml

For information, promethazine is a neuroleptic antihistamine inhibitor of H1 receptors of the phenothiazine family. It is a medicine used in the treatment of allergy (like rhinitis) and transient insomnia.

To respond to this exercise, it is necessary to cross-multiply.

In the antihistamine bottle solution:

25 mg corresponds to 1 ml

11 mg corresponds to: 11/25 = 0.44 ml of the solution.

This 0.44ml is taken from the bottle and put to the syringe.

What volume of a 0.100MHCl0.100MHCl stock solution should be used to prepare 250.00mL250.00mL of 0.0250MHCl0.0250MHCl?​
vladimir2022 [97]
<h3>Answer:</h3>

62.5 mL

<h3>Explanation:</h3>

<u>We are given;</u>

  • Molarity of the stock solution as 0.100 M
  • Volume of the dilute solution as 250 mL
  • Molarity of dilute solution as 0.0250 M

We are required to calculate the Volume of the stalk solution.

  • Taking the volume and molarity of the stock solution to be V₁ and M₁ respectively, and volume and molarity of the dilute solution to be V₂ and M₂ respectively.

We are going to use the dilution formula;

  • According to the dilution formula, M₁V₁ = M₂V₂
  • Rearranging the formula;

V₁ = M₂V₂ ÷ M₁

    = (0.025 M × 0.25 L) ÷ 0.100 M

    = 0.0625 L

But, 1 L = 1000 mL

V₁ = 62.5 mL

Therefore, the volume of the stock solution is 62.5 mL
