Which of the following will show geometrical isomerism?
1-butene
2-butene
2-methyl propene
Propene
B.
2-butene
To show geometrical isomerism the molecules must contain a double bond and each of the two carbon atoms of the double bond must have different substituents which may be same or different on both the carbon atoms. Thus, alkenes of the type abc = cab and abc = cde show geometrical isomerism.
Aromatic properties of benzene are proved by
aromatic sextet theory
resonance theory
molecular orbital theory
All of the above
n-propyl alcohol and iso-propyl alcohol are examples of
position isomerism
chain isomerism
tautomerism
geometrical isomerism
Heating together of sodium ethoxide and ethyl iodide wll give

One mole of a solute A is dissolved in a given volume of a solvent. The association of the solute takes place according to nA [A]n. The van't Hoff factor (i) is expressed as:
i = 1 - x
i = 1 +
i =
i = 1
