2 elements
Explanation:
Octane is composed of carbon and hydrogen atoms.
Answer:
C) differ in the arrangement of their atoms about a double bond
Explanation:
Cis-trans isomers -
Isomers are the molecules which have the same molecular formula but they differ in their arrangement of atoms.
The two isomers possible are the cis and the trans isomer .
1. Cis - isomer - The priority group or the similar group are at same side of the double bond .
2. trans - isomer - The priority group or the similar group are at different side of the double bond . ( the group are diagonally present )
Hence , the option about cis - trans isomer is ( c ) .
