Question

What are the names of the following alkanes? (spelling counts)

FormulaNames
1. C3H8
2. C6H14
3. CH4
4. C8H18

Answer 1

The given alkane molecular formulas C3H8, C6H14, CH4, and C8H18 are named propane, hexane, methane, and octane, respectively, according to the number of carbon atoms they contain.

Step-by-step explanation:

The names of the straight-chain alkanes with the given molecular formulas are as follows:

1. C3H8 is called propane.
2. C6H14 is called hexane.
3. CH4 is called methane.
4. C8H18 is called octane.

These names are derived from the number of carbon atoms in the chain, followed by the suffix -ane to indicate that they are alkanes. The meth-, eth-, prop-, and corresponding prefixes denote one, two, three, and so on carbon atoms respectively.
