Methane is the least soluble in water due to its nonpolar nature.

Pentene has the highest boiling point due to its larger molecular size and increased van der Waals forces.

2-methylpropene is more reactive towards electrophilic addition due to steric hindrance being lower compared to other options.

2-Butene is more stable than 1-Butene due to hyperconjugation and steric hindrance.

2-Butene is more stable than 1-Butene due to hyperconjugation and steric factors.

2-butyne is a symmetrical alkyne.

Acetylene (ethyne) is the most acidic among the given alkynes due to the sp hybridization of carbon.

2-butyne is more stable than 1-butyne due to steric hindrance and hyperconjugation.

Ethyne (C2H2) is the simplest alkyne.

All types of amines can form hydrogen bonds with water due to the presence of the nitrogen atom.

Primary amines can form hydrogen bonds due to the presence of a hydrogen atom attached to the nitrogen.

Aniline has the highest boiling point due to its ability to form strong hydrogen bonds.

Methylamine is a strong base compared to the others due to the lack of resonance stabilization of the lone pair.

Aniline is an aromatic amine because it contains a benzene ring.

Tert-butylamine is least soluble in water due to its bulky structure which hinders hydrogen bonding.

Dimethylamine is the most basic due to the electron-donating effect of the two methyl groups, which increases the electron density on the nitrogen.

Cysteine is the amino acid that contains a sulfur atom in its side chain, which can form disulfide bonds.

Lysine is an essential amino acid that must be obtained through the diet, while glycine, alanine, and serine can be synthesized by the body.

Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information.

Maltose is a disaccharide formed from two glucose units.

Fructose is a ketose sugar, while glucose and galactose are aldoses.

Maltose is a reducing sugar because it has a free aldehyde or ketone group, while sucrose does not.

Cellulose is not digestible by humans due to the lack of enzymes to break it down.

Oxalic acid is a dicarboxylic acid as it contains two carboxyl groups (-COOH).

Stearic acid is a long-chain fatty acid and is solid at room temperature.

C3H6O (acetone) is a ketone, characterized by the carbonyl group (C=O) between two carbon atoms.

Tollen's reagent can oxidize aldehydes but not ketones. Acetone is a ketone and will not react.

Decarboxylation of a carboxylic acid typically yields an alkane.

Decarboxylation of sodium acetate yields methane.

2-bromobutane can undergo elimination to form both 1-butene and 2-butene.
