Answer 2

The complete Flowchart is given as below.

CH4, C2H6, C3H8, C4H10, C5H12

Explanation:

• Alkanes are saturated hydrocarbons because they have a single bond between hydrogen and a carbon atom.
• The simplest alkane is methane i.e CH4.
• Their general formula is CnH2n+2.
• The complete Flowchart is given as below.
• CH4, C2H6, C3H8, C4H10, C5H12
• All the alkanes are obtained by putting the values in their general formula.
• As we keep adding the numbers their molecular weight also increases.
