Question

Please explain in full detail.

2. (21) Give proper names for the following compounds:

Answer 1

1-ethyleyclohex-1-ene -ethyl group 6 2 4 3 it is clear from the above structure that ethyl group is substituent at first position and the double bond is present at the same carbon atom, therefore, IUPAC name is 1-ethylcyclohex-1-ene CI (E)-2-chlorohept-2-ene 1 4 CI 7 5 it is clear from the above structure that chlorine atom is substituent at second position and the double bond is present at the same (second position)carbon atom, double bond is presnt in trans manner therefore, IUPAC name is (E)-2chlorohept-2-ene

1 CI 2 H E configuration 2 5 7 6 c) 1 4 (Z)-3,5,6-trimethylhept-3-ene it is elear from the above structure that methylgroups are substituents at 3,5 and 6 positions and the double bond is present at 3 position carbon atom, double bond is presnt in cis manner therefore, IUPAC name is (Z)-3,5,6-trimethylhept-3-ene Z-configuration 2 2H
