Question

4) Provide the structure of 1,3,5-heptatriene. 5) Provide the proper IUPAC name for the alkene shown be CH3 CH2 CH2 CH3 С=С CH3 CH2 CH3

Answer 1

Answer 4) 1,3,5-heptatriene I-am I-rou 6 7 =Ľ - CH3 1. He C=CCH CH₂ CH₂ et3 CHHC CH 1st of all numbering the long chain Carbon atom, hot Numbering shoud be done from the site where double bond comes in the nearer position. Then indentify whether the compound is cis or trans or. E or 2 configuration . from the nearer post and is cis

ER EM - EM - EN HC - 50 - #cc6 Ethyl and propyl group get the higher priority than the methyl group. So the compound is in E configurat iguration IUPAC Name of the compound is (3E)- 3,4-dimethyl hept-3-one Ist of all double bond get the 1st priority where the methyl group is attached I UPAC Name of the compound is - 3- bromo-1-methyl cyclopenta -1,4-diene Bromo come first because B comes alphabetically - first than m .
