Answer:
(4) option is correct
Explanation:
Given that,
The conformation of 2-methyl-3-pentanol, as viewed along the C₂-C₃ bond.
We need to find the Newman structures
Using given structures
The structure of 2- methyl-3- pentanol is shown in figure.
Through C₂-C₃ carbon shown the structure of Newman projection in figure.
Here, carbon 2 is in front side and carbon 3 is in back side in the figure.
Hence, (4) option is correct.
<span>Reaction of ethane combustion:
2C2H6 (g) + 7O2 (g) ----> 4CO2 (g) + 6H2O
According to the reaction, we can see that </span>C2H6 and CO2 have following stoichiometric ratio:
n(C2H6) : n(CO2) = 2 : 4
If we know the number of moles of ethane we can calculate moles of carbon dioxide:
2 x n(CO2) = 4 x n(C2H6)
n(CO2) = 2 x n(C2H6)
n(CO2) = 2 x 5.4 = 10.8 mole of CO2 <span>are produced</span>
That depends on what the reaction is. Do you have more info related to this problem?
