Answer:
Cis- and trans-3-hexene are symmetric hydrocarons that give only one major product i.e 3-hexanol upon hydroboration.
Explanation:
During hydroboration of 3-hexene, borane (BH3) is added to the double bond of hexene, that transfers the hydrogen atoms to that carbon which becomes is bonded to the boron. The process of hydroboration is created in two steps that leads to the formation of 3-hexanol and boric acid. (please see figure)
Now, the two stereoisomers, Cis- and trans-3-hexene both will give off the 3-hexanol upon hydroboration and the structure of these are illustrated in the figure.
Many chefs today are taught using a culinary arts book written in 1903.
This Is "TRUE"
Nitric acid (HNO₃) is a strong acid. Hence, it completely dissociates into ions as H⁺ and NO₃⁻ in water.
The balanced equation is;
HNO₃(aq) →H⁺(aq) + NO₃⁻(aq)
The stoichiometric ration between HNO₃(aq) and H⁺(aq) is 1 : 1
Hence, the [H⁺] = <span>3.76 x 10</span>⁻²<span> M</span>
Atoms are made up of protons , electrons and neutrons ..,, Atoms of the same element with different number of neutrons are called isotopes. Saying that substance “contains only one type of atom “ really means that it contains only atoms that all have the same number of protons .
