I
CH₃

Answer 2

Answer : The correct option is, 3-methyl-1-pentene

Explanation :

As per given options,

Heptyne : The formula of this compound is,
`C_7H_(12)`. In this compound there are 7 number of carbon atoms and 12 number of hydrogen atoms.

3-methyl-1-pentene : The formula of this compound is,
`C_6H_(13)`. In this compound there are 6 number of carbon atoms and 13 number of hydrogen atoms.

2-methyl-propane : The formula of this compound is,
`C_4H_(10)`. In this compound there are 4 number of carbon atoms and 10 number of hydrogen atoms.

3-ethyl-hexane : The formula of this compound is,
`C_8H_(18)`. In this compound there are 8 number of carbon atoms and 18 number of hydrogen atoms.

Hence, 3-methyl-1-pentene molecule contains a total of six carbon atoms.
