16
Q

What determines the rate of a reaction

A

The slowest step

17
Q

How is the energy represented on a graph for a reaction

A

The 1st transition state requires the most amount of energy.
The second transition state requires less energy.

18
Q

What is the potential energy of the product when the product is favored

A

Lower than the initial potential energy

19
Q

How is an acid base reaction different from an electrophilic reaction

A

Only one product is formed in an electrophilic reaction

20
Q

Define: Hydrohalogenation reaction

A

Hydrogen and halogen is added to a carbon chain.

21
Q

Define: Halogenation

A

A reaction where only a halogen is added.

22
Q

What happens when water is the solvent in an electrophilic reaction

A

An alcohol group (OH) takes the place in a substituent.

23
Q

What is the difference between a symmetrical and a-symmetrical electrophilic reaction

A

different products are formed in an a-symmetrical reaction

24
Q

How does stability affect a cation

A

The more stable the cation the more likely the electrons will attach to it.

25
Q

What is the order of carbon cation stability

A

Tertiary – secondary – primary

26
Q

Markonviks rule

A

Hydrogen goes to the atom with the most number of hydrogens

27
Q

Define: regioselective

A

product is dependent on the region

28

A

False

29
Q
