Question 1

What is the lewis structure of chlorate?

Answer 1

Chlorate is ClO3-

Question 2

Large substituents in a chair conformation are more stable in what configuration?

Answer 2

Equatorial position

Question 3

What is the reaction of combustion?

Answer 3

CH4 + 2O2 –> CO2 + 2H2O + heat

Question 4

What type of molecules have high heats of combustion vs low heat of combustion

Answer 4

Stable molecules have very low heats of combustion

Unstable molecules have very high heats of combustion

Question 5

Rank the following by increasing heat of combustion:

cyclobutane,benzene, cyclopropane, cyclooctane,

Answer 5

Benzene will have the lowest heat of combustion

Thene cyclooctane

Cyclobutane

Cyclopropane

Cyclopropane is the most unstable and it is more unstable than cycloctane

Question 6

What makes a radical stable vs unstable

Answer 6

The more substituted a radical the more stable

This is why allylic radicals are more stable because of resonance followed by tertiary radical, secondary radical, primary radicals are the least stable

Question 7

If you start out with CH2 = CH2 and want to turn it into CH3 - CH3 what do you react it with?

i.e, how do you form an alkane from an alkene

Answer 7

H2/Pd (catalyst)
