The Correct Option is C

Solution and Explanation

The correct option is (C) : Spatial arrangement of atoms 

The isomers that differ from one another in terms of their geometry or atoms' spatial arrangement are known as geometric isomers, also known as cis-trans isomers or EZ isomers. Double bonds and ring structures are the two primary sources of geometric isomers. In contrast to limited rotation about the double bond, which emphasises the relative locations of the substituent groups above and below the double bond, the C-C single bond has unrestricted rotation.

Alkenes

Alkenes

In organic chemistry, an alkene is a hydrocarbon containing a carbon-carbon double bond.[1]

Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.

IUPAC Nomenclature of Alkenes

  1. An alkene or cycloalkene is indicated by the suffix (ending) ene.
  2. For the root name, the longest chain must include both carbon atoms of the double bond.
  3. The root chain must be numbered beginning at the end closest to a double bond carbon atom. If the double bond is in the chain's centre, the nearest substituent rule is used to determine where the numbering begins.
  4. If the compound contains more than one double bond, it is named with a diene, triene, or equivalent prefix indicating the number of double bonds, and each double bond is assigned a locator number.
