1-butanol has the hydroxyl group (-OH) attached to a primary carbon atom, making it a primary alcohol.

Ethylamine (C2H5NH2) is a primary amine as it has one alkyl group attached to the nitrogen atom.

The zinc-carbon battery is a type of primary cell, which cannot be recharged.

Halogens exist as diatomic molecules (e.g., Cl2, F2).

C2O4^2- (oxalate ion) is oxidized to CO2, thus it acts as a reducing agent in this reaction.

Hexanoic acid is a saturated carboxylic acid.

Stearic acid is a saturated fatty acid, meaning it has no double bonds between carbon atoms.

Cyclohexane is a saturated hydrocarbon, containing only single bonds.

2-Pentanol has the hydroxyl group attached to a secondary carbon, making it a secondary alcohol.

Hydrochloric acid (HCl) is a strong acid that completely dissociates in water.

Hydrochloric acid (HCl) is a strong acid.

Formic acid is considered a stronger carboxylic acid compared to the others listed.

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

Bakelite is a thermosetting polymer, while the others are thermoplastics.

Colligative properties depend on the number of solute particles in a solution, and boiling point elevation is one such property.

Nylon-6,6 is a condensation polymer formed by the reaction of hexamethylenediamine and adipic acid.

Lightning is an example of plasma, which is a state of matter consisting of ionized gas with free electrons.

Alkanes are saturated hydrocarbons with the general formula CnH2n+2. C3H8 (propane) fits this formula.

Propene is an alkene, characterized by a carbon-carbon double bond.

Propene is an alkene, characterized by a carbon-carbon double bond.

Butyne is an alkyne, characterized by a triple bond between carbon atoms.

Physisorption involves weak Van der Waals forces, and the adsorption of water on silica gel is a classic example of this type of adsorption.

Not all p-block elements are metals; many are nonmetals and metalloids.

Transition metals generally have high density, not low density.

Aldehydes contain the functional group -CHO, which is characterized by a carbonyl group (C=O) bonded to a hydrogen atom.

P2O5 is the most acidic oxide among the given options, as it forms phosphoric acid in water.

Formic acid (HCOOH) is the strongest carboxylic acid among the given options due to the presence of a hydrogen atom directly attached to the carbonyl carbon, which increases its acidity.

CN- is a strong field ligand that causes a large splitting of d-orbitals, leading to low-spin complexes.

Water (H2O) has a polar covalent bond due to the difference in electronegativity between hydrogen and oxygen.

Water (H2O) has a polar covalent bond due to the difference in electronegativity between hydrogen and oxygen.
