Question

Ch3-c=ch-c=ch2 | | Ch3 Ch3

Answer 1

Если нужны названия, то: CH₃-CH=CH-CH=CH₂ (у вас неправильная формула, научитесь считать, советую), эта формула пентадиен - 2,4.

С₂H₆ - этан.

Answer 2

The chemical structure you provided seems to represent a molecule with the following structure:

mathematicaCopy code
   CH3
     \
CH3-C=CH-C=CH2
     /
   CH3

In this molecule, there are four carbon atoms arranged in a chain. The carbon atoms are bonded together with alternating single and double bonds, forming a conjugated system of double bonds. The molecule also contains hydrogen atoms attached to some of the carbon atoms.

The systematic name of this molecule would be "2,4-octadiene," where the "2,4" refers to the positions of the double bonds in the chain. Additionally, there are two methyl (CH3) groups attached to two of the carbon atoms.

Please note that I have assumed the correct arrangement of the atoms based on the given representation. If there was any specific question or context you had in mind regarding this molecule, feel free to ask!
