Alkynes are characterized by the presence of a triple bond between carbon atoms.

All alcohols contain a hydroxyl group (-OH) as their functional group.

All amino acids contain a carboxylic acid group (-COOH) along with an amino group (-NH2).

Amines contain an amino group (-NH2) as their functional group.

Amino acids contain both an amino group and a carboxyl group.

Amino acids contain both an amino group and a carboxyl group, which are also present in proteins.

Carboxylic acids contain the carboxyl functional group (-COOH), which is a combination of a carbonyl and a hydroxyl group.

Haloalkanes contain a halogen functional group, which is responsible for their reactivity and properties.

Phenols contain a hydroxyl group (-OH) directly attached to an aromatic ring.

The compound contains a benzaldehyde functional group (aldehyde) along with hydroxy and methoxy substituents.

The compound CH3-CH2-COOH contains a carboxylic acid functional group, characterized by the -COOH group.

The compound contains a carbonyl group (C=O) between two carbon atoms, classifying it as a ketone.

The compound contains a carboxylic acid functional group (-COOH) at the end of the carbon chain.

The compound contains a carbonyl group (C=O) between two carbon atoms, which is characteristic of ketones.

The compound CH3-COOH contains a carboxylic acid functional group, characterized by the -COOH group.

The compound CH3CH2COOH contains a carboxylic acid functional group, characterized by the -COOH group.

The amino group (-NH2) attached to the alpha carbon contributes to the chirality of amino acids.

Tertiary alkyl halides favor the S_N1 mechanism due to steric hindrance, leading to the formation of a carbocation intermediate.

Tertiary alkyl halides favor the S_N1 mechanism due to steric hindrance and the stability of the carbocation.

The reaction will proceed via the SN1 mechanism due to the tertiary carbon, which stabilizes the carbocation intermediate.

Electrophilic aromatic substitution primarily follows a mechanism similar to SN1, involving the formation of a carbocation intermediate.

The reaction of alkenes with bromine involves an electrophilic addition mechanism, where the alkene acts as a nucleophile and attacks the electrophilic bromine molecule.

PCl5 has a trigonal bipyramidal geometry due to the sp3d hybridization of phosphorus, accommodating five bonding pairs.

Benzene (C6H6) exhibits resonance due to the delocalization of electrons in the sp2 hybridized carbon atoms forming a cyclic structure.

Real gases deviate from ideal behavior at high pressures due to increased intermolecular forces and the volume occupied by gas molecules.

Lipids, particularly triglycerides, are primarily responsible for energy storage in animals.

2-hexene has a double bond that allows for cis and trans configurations.

2-butanol has a chiral center and can exist as two enantiomers, thus exhibiting optical isomerism.

2-bromobutane can undergo E1 elimination due to the stability of the carbocation formed during the reaction.

Tertiary alkyl halides are most favorable for E2 reactions, but primary and vinyl halides can also undergo E2 under certain conditions.
