Question

Ch2=c(c2h5)ch2ch2ch3 give the iupac name for this compound.

Answer 1

IUPAC name of the compound is 2-ethyl pent-1-ene.

• Numbering the main chain from the most prior double bond we get a five-membered long carbon chain. So, pent comes.
• Again the double bond is present at C-1 so, pent-1-ene comes.
• Again, the ethyl group is present at C-2 so, 2-ethyl comes.
• Hence the IUPAC name of the compound is 2-ethyl pent-1-ene.
