chemical reactions of alkanes, alkenes and alkynes

Which of the statements are WRONG about the nucleophilic addition reaction of alkenes and alkynes?

Naming of alkenes and Alkynes

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. Write the major product of the reaction : (CH_(3))_(3)C-CH=CH_(2)overset(HBr)to
