The materials that we use to make plastic bags, crayons and polyester (for clothes) come from petroleum products

Explanation:

Plastics from which plastic bags are obtained by fractional distillation of crude oil. Crude oil is mixture of several components that can be obtained at different stages of the fractional distillation.

Naphtha, a vital component used in preparation of plastics is also got from petroleum. similarly paraffin wax which is used to make crayons is also obtained during the fractional distillation of petroleum. similarly the acids and alcohol required to produce polyester also comes from petroleum.

Answer:

1) acetylide

2) enol

3) aldehydes

4) tautomers

5) alkynes

6) Hydroboration

7) Keto

8) methyl ketones

Explanation:

Acetylide anions (R-C≡C^-) is a strong nucleophile. Being a strong nucleophile, we can use it to open up an epoxide ring by SN2 mechanism. The attack of the acetylide ion occurs from the backside of the epoxide ring. It must attack at the less substituted side of the epoxide.

Oxomercuration of alkynes and hydroboration of alkynes are similar reactions in that they both yield carbonyl compounds that often exhibit keto-enol tautomerism.

The equilibrium position may lie towards the Keto form of the compound. Usually, if terminal alkynes are used, the product of the reaction is a methyl ketone.

What is the empirical formula of propene CH3 CH2 CH2

kiruha [24]

Answer:

CH

Explanation:

Molecular formula of propene : C₃H₆

Take the HCF of carbon and hydrogen atoms :

3 = 3
6 = 2 x 3

Then, we can write the formula as :

3CH
This means there are 3 moles present

Empirical Formula :

Molecular Formula / No. of moles
C₃H₆ / 3
CH

The empirical formula of propene is CH

Suppose that 7.25 x 10^22 atoms of a hypothetical element have a mass of 3.88 g. What would be the molar mass (g/mol) of this el

S_A_V [24]

Answer:

32.23 to 4 significant figures.

Explanation:

The molar mass of the element is the mass of 6.022 * 10^23 atoms (Avogadro's number).

So by proportion it is 6.022 * 10^23 * 3.88 / 7.25 * 10^22

= 32.23 to 4 significant figures.
