Which answer provides the correct name for the following hydrocarbon?
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
In the given molecule, there are five carbon atoms attached linearly to each other will single bonds only.
So, it is known that when a compound contains only carbon and hydrogen atoms attached single bondedly to each other then this type of hydrocarbon is known as alkane.
Their general formula is , where n is the number of carbon atoms present. Suffine "ane" is added to the name of alkane.
Thus, we can conclude that name of the given hydrocarbon is pentane.

Answer:
n = 6.06 x mol
Explanation:
n =?
m = 3.06 x 10-³ g
M (H5) = 5 x 1.01 (Since we only want hydrogen)
Atomic mass of C = 12.01
Atomic mass of H is 1,01, etc.
Having this data, we can use the Molar mass formula and change it so we can know the quantity of matter (n) in moles, and we just replace it.
M = ⇔ n =
⇔ n =
⇔ n = 6.06 x
mol
