12.53 (syn) show how each of these compounds can be produced from an alkene or alkyne. draw the appropriate alkene or alkyne and
1 answer:
The structures of alkanes and alkynes are given below in the diagram.
In organic chemistry, when an organic compound contains atoms joined only by single covalent bonds, the compound is said to be saturated and this saturated hydrocarbons are known as alkanes. For example propane that is shown in the diagram attached below. When an organic compound contains carbon atoms joined by double(alkene) or triple(alkyne) covalent bonds, the compound is said to be unsaturated. For example propene and propyne as shown in the diagram.
Furthermore, the hydrocarbons that possess a set of carbon-carbon double covalent bonds,>C=C<, in their carbon chains form the homologous series called alkenes while those possessing a set of carbon-carbon triple covalent bond in their carbon chains form the alkyne series.

There is some info missing. I think this is the original question.
<em>Calculate the percent ionization of nitrous acid in a solution that is 0.249 M in nitrous acid. The acid dissociation constant of nitrous acid is 4.50 × 10 ⁻⁴.</em>
<em />
Step 1: Given data
Initial concentration of the acid (Ca): 0.249 M
Acid dissociation constant (Ka): 4.50 × 10 ⁻⁴
Step 2: Write the ionization reaction for nitrous acid
HNO₂(aq) ⇒ H⁺(aq) + NO₂⁻(aq)
Step 3: Calculate the concentration of nitrite in the equilibrium ([A⁻])
We will use the following expression.
Step 4: Calculate the percent ionization of nitrous acid
We will use the following expression.
