2-methylpropane

Question 4

In a Newman projection of butane looking down the $$C_2$$-$$C_3$$ bond, which conformation is the most stable?

Accepted Answer

Anti conformation

Question 5

Which of the following best describes a tertiary carbon atom?

Accepted Answer

A carbon atom bonded to three other carbon atoms

Question 6

Which of the following compounds is classified as a ketone?

Accepted Answer

Acetone

Question 7

Which of the following functional groups is present in acetic acid?

Accepted Answer

Carboxylic acid

Question 8

Which of the following statements about halides is correct?

Accepted Answer

The carbon-halogen bond is polarized, making the carbon electrophilic.

Question 9

Which of the following is the correct condensed structure for 2-methylpropane?

Accepted Answer

CH_3CH($$CH_3$$)$$CH_3$$

Question 10

Which of the following best explains why cyclohexane adopts a chair conformation?

Accepted Answer

To minimize angle strain and torsional strain

Question 11

Which of the following is a correct statement about the physical properties of alkanes as the number of carbons increases?

1-Propanol

Question 13

Which of the following best describes the difference between a primary and a secondary amine?

Accepted Answer

A primary amine has one alkyl group attached to nitrogen, while a secondary amine has two.

Question 14

Which of the following is a correct statement about the stability of chair conformers of cyclohexane?

Accepted Answer

The chair conformer with bulky substituents in the equatorial position is more stable.

Question 15

Which of the following is a correct skeletal structure for 2-butanone?

Accepted Answer

$$CH_3COCH_2CH_3$$

Question 16

Which of the following best explains why ethers have lower boiling points than alcohols of similar molecular weight?

Ethers cannot form hydrogen bonds with themselves.

Question 17

Which of the following is the correct classification for the carbon atom in $$CH_3CH_2CH_2Br at $$the position bonded to Br?

Accepted Answer

Primary carbon

Question 18

Which of the following is a correct statement about the reactivity of alcohols?

Accepted Answer

Alcohols can act as nucleophiles due to the lone pairs on oxygen.

Question 19

Which of the following is a correct IUPAC name for the compound with the structure $$CH_3CH_2COOH$$?

Accepted Answer

Propanoic acid

Question 20

Which of the following best describes the effect of ring strain in cyclopropane compared to cyclohexane?

Accepted Answer

Cyclopropane has much higher ring strain due to its bond angles being far from the ideal tetrahedral angle.
