isomerism of alkenes

What is the cause of geometrical isomerism in alkenes ?

a) Arrange benzene, n-hexane and ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour. b) Write the structural formulae and IUPAC names for all the structural isomers of alkenes with molecular formula C_(5)H_(10) . c) Write the various types of isomerism shown by alkenes. Give one example of each.

How many minimum no. of C-atoms are required for position & geometrical isomerism in alkene ?

Geometrical Isomerism In Alkenes

Alkenes and alkynes are unsaturated hydrocarbons and undergo electrophilic addition reactions. In alkenes, the addition occurs in one step while in alkynes the addition occurs in two steps. Alkenes show geometrical isomerism but alkynes do not. Alkynes are more acidic than alkenes which are more acidic than alkanes. Both alkenes and alkynes can be prepared by the electrolysis of sodium or potassium salts of carboxylic acids. Which of the following molecule can exhibit geometrical isomerism ? 2-Methylbut-2-en-1-ol , 3-Methylbut-2-en-1-ol

Alkenes show geometrical isomerism but alkynes do not. Alkynes are more acidic than alkenes which are more acidic than alkanes. Both alkenes and alkynes can be prepared by the electrolysis of sodium or potassium salts of carboxylic acids. Write the major product of the reaction : (CH_(3))_(3)C-CH=CH_(2)overset(HBr)to

An alkyl halide of formula C_6 H_13 Br on treatment with potassium t-butoxide gives two isomeric alkenes dimethy butane. Isomeric alkene are :
