SN2 reactions are bimolecular, meaning the rate depends on the concentration of both the substrate and the nucleophile.

S_N2 reactions are bimolecular and involve a direct attack by the nucleophile, leading to a concerted mechanism without a carbocation.

Cis isomers typically have higher boiling points than their trans counterparts due to increased polarity.

Condensation polymerization typically involves the reaction of two different monomers, resulting in the release of small molecules such as water or methanol.

Diastereomers are not mirror images and typically have different physical properties.

E2 reactions occur in a single concerted step where the base abstracts a proton while the leaving group departs.

Electrochemical cells convert chemical energy into electrical energy, which is a fundamental characteristic of these systems.

Enantiomers are non-superimposable mirror images and rotate plane-polarized light in opposite directions.

F-block elements have partially filled f-orbitals, which is a defining characteristic of these elements.

Physisorption is characterized by weak van der Waals forces, making it a reversible process with low heat of adsorption.

Saturated fatty acids contain no double bonds and typically have a higher melting point than unsaturated fatty acids.

Stereoisomers have the same connectivity but differ in the spatial arrangement of atoms.

Werner complexes can exhibit isomerism due to different arrangements of ligands around the central metal atom.

Amines typically have a fishy odor due to their structure and are known for their ability to form hydrogen bonds.

Alkynes can undergo hydrogenation, hydrohalogenation, and halogenation reactions, making all of the above options characteristic reactions.

2-butanol has a chiral center at the second carbon, making it chiral.

Aromatic compounds are widely used in the production of dyes, pharmaceuticals, and plastics, making them versatile in various applications.

Surface chemistry plays a crucial role in various applications, including catalysis, drug delivery, and environmental cleanup.

Bromine is a common electrophile used in electrophilic aromatic substitution, often activated by a Lewis acid.

The nitronium ion (NO2+) is the active electrophile in the nitration of benzene, generated from nitric acid and sulfuric acid.

All of the listed tests (Benedict's, Tollens', and Fehling's) can be used to identify aldehydes.

Stereoisomers have the same connectivity of atoms but differ in their spatial arrangement.

The functional group characteristic of alkynes is the triple bond represented as -C≡C-.

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

2,3-butanediol is a meso compound because it has two chiral centers but is superimposable on its mirror image.

The –NO2 group is a meta-directing group because it withdraws electrons from the aromatic ring, directing incoming electrophiles to the meta position.

Aromatic amines can be prepared by the reduction of nitro compounds.

C6H5OH contains a hydroxyl group (-OH) directly attached to a benzene ring, making it a phenol.

D-block elements typically have high melting and boiling points due to strong metallic bonding.

Alkenes are widely used in the manufacturing of plastics, such as polyethylene and polypropylene.
