☆Chain isomers:

》Those which has same structural and molecular formula but differs in the number of carbon atoms in parent chain.

☆Solution:

》pent-2-ene has 5 carbon atoms in its parent chain.

• molecular formula(MF)= \ C_5 H_{10}

a) 2-methyl-but-2-ene

  • MF = \ C_5 H_{10}
  • parent chain includes 4-carbon atoms.
  • \rm chain\;isomer

b) 1-Ethyl prop-1-ene

  • MF = \ C_5 H_{10}
  • after rearranging it has 5-carbons in parent chain.
  • \rm identical

c) pent-3-ene

  • MF= \ C_5 H_{10}
  • parent chain had 5carbon atoms.(rearranging)
  • \rm Position \;isomer

d)2-methyl pentane

  • MF = \ C_6 H_{14}
  • parent chain has 6 carbon.
  • \rm Not\;any\;isomer

Above observations and definitions we can say 2-methyl-but-2-ene is chain isomer of pent-2-ene.
