Question 1

The compound below is a secondary alkyl halide.

Accepted Answer

The answer of The compound below is a secondary alkyl...

Question 2

Alkyl halides are soluble in water when the alkyl group has less than five carbons.

Accepted Answer

Alkyl halides are generally insoluble in water regardless of the size of the alkyl group, due to their nonpolar nature which makes them incompatible with water's polar nature.

Question 3

The alcohol shown below can be oxidized with K₂Cr₂O₇ to give the indicated product.

Accepted Answer

The answer of The alcohol shown below can be oxidized...

Question 4

CHCl₂F is classified as a CFC.

Accepted Answer

CHCl₂F is not a standard notation for chlorofluorocarbons (CFCs) or any chemical compound; CFCs are typically denoted by a formula such as CCl3F, indicating the presence of carbon (C), chlorine (Cl), and fluorine (F) atoms.

Question 5

Ethers are organic compounds that have two alkyl groups bonded to an oxygen atom.

Accepted Answer

Ethers are characterized by having an oxygen atom connected to two alkyl or aryl groups, represented by the general formula R-O-R', where R and R' can be either alkyl or aryl groups.

Question 6

In the simple sugar D-glucose (structure shown),there are two primary -OH groups.

Accepted Answer

The answer of In the simple sugar D-glucose (structure shown),there...

Question 7

Cyclopentanol has a higher boiling point than methylcyclopentane.

Accepted Answer

Cyclopentanol has a higher boiling point due to the presence of a hydroxyl group (-OH) which allows for hydrogen bonding, a strong intermolecular force, whereas methylcyclopentane lacks this functionality and relies on weaker van der Waals forces.

Question 8

The compound below is expected to be soluble in water.

Accepted Answer

The answer of The compound below is expected to be...

Question 9

The alcohol shown below can be oxidized with K₂Cr₂O₇ to give the indicated product.

Accepted Answer

The answer of The alcohol shown below can be oxidized...

Question 10

Propyl bromide is a primary alkyl halide.

Accepted Answer

Propyl bromide, also known as 1-bromopropane, has its bromine atom attached to the first carbon in the chain, making it a primary alkyl halide.

Question 11

Thiols are oxidized to sulfates.

Accepted Answer

Thiols are typically oxidized to disulfides or sulfonic acids, not sulfates.

Question 12

Antabuse,a drug given to alcoholics to prevent them from consuming alcoholic beverages,acts by interfering with the normal oxidation of ethanol. Antabuse inhibits the oxidation of ethanol to acetaldehyde.

Accepted Answer

Antabuse (disulfiram) works by inhibiting the enzyme acetaldehyde dehydrogenase, which is involved in the metabolism of ethanol, leading to an accumulation of acetaldehyde when alcohol is consumed, causing unpleasant effects.

Question 13

The IUPAC name of the compound below is 2-pentanol.

Accepted Answer

The answer of The IUPAC name of the compound below...

Question 14

CH₃CH₂CH₂CH₂Cl has a higher melting point than CH₃CH₂CH₂CH₂Br.

Accepted Answer

CH₃CH₂CH₂CH₂Br has a higher melting point than CH₃CH₂CH₂CH₂Cl because bromine is larger and has stronger van der Waals forces compared to chlorine.

Question 15

Thiols have higher boiling points and melting points than alcohols having the same size and shape.

Accepted Answer

Alcohols have higher boiling points and melting points than thiols of the same size and shape because the hydroxyl (-OH) group in alcohols can form stronger hydrogen bonds compared to the thiol (-SH) group.

Question 16

Two ether molecules can form hydrogen bonds with each other.

Accepted Answer

Ether molecules lack a hydrogen atom directly bonded to a highly electronegative atom (like oxygen or nitrogen), which is necessary for hydrogen bonding.

Question 17

The two alcohols below are dehydrated with H₂SO₄ to give the same major product.

Accepted Answer

The answer of The two alcohols below are dehydrated with...

Question 18

The compound below is expected to be soluble in water.

Accepted Answer

The answer of The compound below is expected to be...

Question 19

Ethers have stronger intermolecular forces than alkanes but weaker intermolecular forces than alcohols.

Accepted Answer

Ethers have dipole-dipole interactions due to their polar C-O bonds, making their intermolecular forces stronger than those in nonpolar alkanes, which only have London dispersion forces. However, ethers lack hydrogen bonding, which is present in alcohols, making their intermolecular forces weaker than those in alcohols.

Question 20

CH₃CH₂CH₂CH₂-S-S-CH₂CH₂CH₃ is an example of a disulfide compound.

Accepted Answer

The compound contains a -S-S- linkage, which is characteristic of disulfide compounds.
