1. Describe properties about alkenes and alkynes. 2. The two stereoisomers of l-bromo-1,2-dichloroethene cannot be designated as cis and trans in the normal way because the double bond is trisubstituted. They can, however, he given (E) and (Z) designations. Write a structural formula for each isomer and give each the proper designation 3. Studies of numerous alkenes reveal a pattern of stabilities that is related to the number of alkyl groups attached to the carbon atoms of the double bond....

QUESTION 2 1. Which one of the following statements is true? (HX is either HCl or HBr) Alkynes undergo electrophilic substitution reactions with HX to give halogenated alkenes. Adding an excess of HX to an alkyne gftens times will stop the reaction at the alkene step instead of forming the halogenated alkane. When adding one mole of HX to an alkyne, regioselective Markovnikov addition is observed for the alkene product typically exhibiting trans stereochemistry When adding one mole of HX...

Passage 11 (Questions 1-9) Dienes, a special group of alkenes, can be classified as conjugated or isolated. Conjugated dienes are alkenes with alternating double and single bonds. Isolated dienes have double bonds separated by more than one single bond. One explanation for this observation is the hybridization theory. According to the hybridization theory, the stability of conjugated dienes comes from the hybridization of the orbitals forming the carbon-carbon single bonds. For example, in 1,4-pentadiene, the C-C single bonds result from...
