Exploring Haloalkanes and Haloarenes

What is the IUPAC name for CH3CH2Cl?

• ethyl chloride

• chloroethanol

• 1-chloropropane

• 1-chloroethane

How do you name a haloalkane with a branched chain?

• Ignore halo groups when naming

• Count all carbon atoms in the molecule

• Use only the longest branch for naming

• Identify the longest chain, number it, name halo groups and branches, combine into a single name.

What type of reaction do haloalkanes typically undergo with nucleophiles?

• Radical substitution

• Electrophilic addition

• Nucleophilic substitution

• Elimination reaction

What is the mechanism of nucleophilic substitution in haloalkanes?

• Nucleophilic substitution is a photochemical process.

• Nucleophilic substitution only occurs via the E1 mechanism.

• Nucleophilic substitution in haloalkanes occurs via SN1 and SN2 mechanisms.

• Haloalkanes undergo elimination reactions exclusively.

Which haloalkane is most reactive in nucleophilic substitution reactions?

• Tertiary haloalkanes

• Alkyl halides

• Secondary haloalkanes

• Primary haloalkanes

What is the effect of the carbon chain length on the boiling point of haloalkanes?

• The boiling point of haloalkanes decreases with increasing carbon chain length.

• The boiling point of haloalkanes remains constant regardless of carbon chain length.

• The boiling point of haloalkanes is unaffected by carbon chain length.

• The boiling point of haloalkanes increases with increasing carbon chain length.

What is the primary product when 1-bromopropane reacts with sodium hydroxide?

• 1-bromopropane

• propanol

• sodium bromide

• propane

How does the presence of halogens affect the acidity of haloarenes?

• Halogens increase the acidity of haloarenes by forming stronger bonds with hydrogen.

• Halogens have no effect on the acidity of haloarenes.

• Halogens increase the acidity of haloarenes by stabilizing the conjugate base.

• Halogens decrease the acidity of haloarenes by destabilizing the conjugate base.

What is the main characteristic of electrophilic aromatic substitution?

• The substitution of a hydrogen atom on an aromatic ring with an electrophile.

• The rearrangement of the aromatic ring structure.

• The addition of a nucleophile to an aromatic ring.

• The removal of an electrophile from an aromatic compound.

Which reagent is commonly used in electrophilic aromatic substitution reactions?

• Reducing agents like lithium aluminum hydride (LiAlH4)

• Electrophiles such as bromine (Br2) with a Lewis acid catalyst.

• Oxidizing agents such as potassium permanganate (KMnO4)

• Nucleophiles like sodium hydroxide (NaOH)
