Elastomers are known for their elastic properties, allowing them to stretch and return to their original shape.

Hydrogen gas (H2) can act as a reducing agent for aldehydes, converting them to alcohols.

H2 in the presence of palladium (Pd) is a reducing agent that can reduce ketones to alcohols.

Fructose is a reducing sugar, while sucrose, starch, and cellulose are not.

2-pentanol has the hydroxyl group on the second carbon, making it a secondary alcohol.

Dimethylamine is a secondary amine as it has two alkyl groups attached to the nitrogen.

Excessive caffeine can lead to insomnia and disrupt sleep patterns.

Glycogen is the storage form of glucose in animals, while starch serves this role in plants.

The -CH3 group is a strong +I effect group as it donates electron density through the inductive effect.

-NO2 is a strong -M group as it withdraws electron density through resonance.

Ammonia (NH3) is a strong nucleophile due to the presence of a lone pair of electrons on the nitrogen atom.

Cellulose is a structural polysaccharide found in the cell walls of plants.

1-butyne is a terminal alkyne because it has a triple bond at the end of the carbon chain.

Alkanes are saturated hydrocarbons with the general formula CnH2n+2. C4H10 (butane) fits this formula.

The –F group is an example of a -I effect as it withdraws electron density through sigma bonds.

All halogens (-F, -Cl, -Br, -I) exhibit -I effect, but -F is the strongest among them.

The –NO2 group withdraws electron density through resonance, exhibiting a -M effect.

Acetaldehyde can exist in two forms (keto and enol) that readily interconvert, demonstrating tautomeric isomerism.

Nylon-6,6 is a copolymer made from two different monomers: hexamethylenediamine and adipic acid.

Sodium lauryl sulfate is a synthetic detergent commonly used in personal care products.

Polyvinyl chloride (PVC) is a synthetic polymer widely used in construction and plumbing.

Penicillin is a well-known antibiotic used to treat bacterial infections.

Pentane and 2-methylbutane differ in the arrangement of carbon atoms, thus showing chain isomerism.

2-pentene can exist in cis and trans forms due to the presence of a double bond.

Lactic acid has a chiral center and can exist as two enantiomers, thus exhibiting optical isomerism.

1-bromopropane and 2-bromopropane differ in the position of the bromine atom, showing structural isomerism.

Keto-enol tautomerism is a classic example of tautomeric isomerism.

The inductive effect is permanent and weakens with distance, but it is not reversible.

Alcohols are not derivatives of carboxylic acids; they are separate functional groups.

Carbohydrates are primarily involved in energy storage, structural support, and cell recognition, but they do not produce hormones.
