Draw all the isomers bond with example

Accepted Answer

Isomers are molecules with the same molecular formula but different structural formulas. Here are some examples:
Structural Isomers:
Butane (C4H10):

n-butane (straight chain): CH3CH2CH2CH3

isobutane (branched chain): CH3CH(CH3)CH3

Pentane (C5H12):

n-pentane: CH3CH2CH2CH2CH3

isopentane: CH3CH(CH3)CH2CH3

neopentane: CH3C(CH3)3
Geometric Isomers (Cis-Trans):
2-butene (C4H8):

cis-2-butene:

H and CH3 groups on the same side of the double bond

trans-2-butene:

H and CH3 groups on opposite sides of the double bond
Enantiomers (Optical Isomers):
2-chlorobutane (C4H9Cl):

(R)-2-chlorobutane:

Chiral center with a clockwise arrangement of groups (R configuration)

(S)-2-chlorobutane:

Chiral center with a counterclockwise arrangement of groups (S configuration)
These are just a few examples of isomers. The number and types of isomers increase with the complexity of the molecule.
