Interpretation:
The relationship should be identified for the structural formula of
Concept introduction:
Isomer: Molecule has same molecular formula but different structural arrangement is called isomer.
Geometric isomerism (also known as E-Z isomerism or cis-trans isomerism): same molecular formula but different arrangement in the space. These isomers happen where you have restricted rotation in a molecule (double bond in the molecule). The
Constitutional isomer: (or structural) isomers differ in the connectivity they contain different functional groups and / or bonding patterns is called constitutional isomer.
Resonance: it is a process of delocalization electrons with in the molecule.
Chiral: Absence of a plane of symmetry or a center of symmetry is called chiral molecule, a non-superimposable on its mirror image is called chiral. A carbon atom is attached by the four different groups is called chiral carbon.

- Are there alkene isomers with the molecular formula C2H3Cl?arrow_forwardThis question is about the chemistry of alkenes, which are unsaturated hydrocarbons. (a) State what is meant by the term unsaturated as applied to a hydrocarbon. (1) (b) An organic compound, X, is an unsaturated hydrocarbon with molecular formula CH₂. (i) Draw the displayed formulae and give the names of two molecules with molecular formula C₂H, which are E/Z isomers. (3) Isomer 1 Isomer 2 Name: Name:arrow_forward(a) how many stereoisomers are possible? (b) how many chiral carbons are in the structure? (c) is this optically active?arrow_forward
- What is an isomer? Name the isomers of the compound with the closed formula C4H9CI. Which of these isomers can have a chiral structure? Examine it from a stereochemical point of viewarrow_forwardWhich of the noncyclic isomers of C4H7F are optically active?arrow_forwardName the isomers of the compound with the closed formula C4H9Cl. Which of these isomers can have a chiral structure? Examine it from a stereochemical point of view.arrow_forward
- Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomersarrow_forwardConstruct models of all the possible stereoisomers of 1,2-dichlorocyclopropane. Using your models, draw structures for and name the isomers. Label each chirality centre R or S. Indicate which pairs are related as enantiomers and which as diastereoisomers.arrow_forwardCan cyclopentene exhibit cis-trans isomerism? Explain.arrow_forward
- (a) Draw the nine isomers having the formula C7H16 . (Hint: There is one structure with a seven-carbon chain, two structures with six-carbon chains [one is illustrated in the margin above], five structures with a five-carbon chain, and one structure with a fourcarbon chain.)(b) Identify the isomers of C7H16 that are chiral.arrow_forwardDraw projection (lewis) drawings of all isomers of C5H12. What type of isomerism do they represnet?arrow_forwardProvide two constitutional isomers of the formula of C5H12 with no tertiary carbons.arrow_forward
