Answer 2

IUPAC Name:

Of the given hydrocarbon:

• $\rm{H_3C - CH = CH - CH2 - CH = CH - CH2 - CH_3}$

Here the single lines represent single bonds and double bonds represent double bonds. The hydrocarbon where carbon-carbon are bonded with double bonds are alkenes

Rules:

• As there is double bond b/w carbon atoms, we will use -ene as suffix.
• The position of double bond as a number should be written before it.
• Then, Count the no. of carbons and name it according. Like 5 means pent.

But....!

Here there is 2 double bonds. Hence,

• Choose the side of the chain from where the double bond is nearer in terms of numbering.

We have:

• No. of carbon atoms = 8 (Oct)
• Numbering from left side.
• Double bond at 2 and 5.

The name would be:

$\Large{ \boxed{ \sf{ \purple{Oct - 2,5 - diene}}}}$
