Quiz | Reactions of Alkanes
Which one of the following statements regarding alkanes is correct?
Alkanes are polar molecules
Alkanes experience dispersion forces
Alkanes are soluble in water
Alkanes have high boiling points
How many groups of equivalent hydrogen does the pentane have?
The alcohol of 2-methylpentan-2-ol is:
The alcohol chemical function is on a carbon attached to 3 other carbon atoms ⇒ it is a tertiary alcohol
What is the first step of the halogenation of alkanes?
Heterolytic cleavage of the dihalogen
Homolytic cleavage of the dihalogen
Radical chain reactions proceed in 3 stages: initiation (homolytic cleavage of the Cl-Cl bond), propagation and termination (radical-radical combination)
How many products do you expect with the halogenation of methylpropane?
What is the most stable radical?
The stability of radicals increases along the series from primary to secondary to tertiary (hyperconjugation). There are no quaternary radicals since carbon atoms cannot have more than 8 electrons in their valence shell
