In a rectangle, opposite sides are equal and all angles are indeed 90 degrees.

Alcohols have higher boiling points than alkanes due to the presence of hydrogen bonding.

Not all alcohols are volatile; for example, long-chain alcohols have lower volatility.

Alcohols have higher boiling points than alkanes due to hydrogen bonding.

Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms.

Alkenes can undergo polymerization due to the presence of a double bond.

Alkynes are generally less reactive than alkenes due to the stability of the triple bond.

Alkynes have a higher boiling point than alkenes due to stronger intermolecular forces.

Amines generally have lower boiling points than alcohols due to the absence of hydrogen bonding in tertiary amines.

Aromatic amines are less basic than aliphatic amines due to resonance stabilization of the lone pair on nitrogen.

Many aromatic compounds can be carcinogenic, such as benzene, which is known to be harmful to human health.

The buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

Carboxylic acids are more acidic than alcohols due to the resonance stabilization of their conjugate base, making the statement 'They are less acidic than alcohols' incorrect.

Carboxylic acids can form hydrogen bonds due to the presence of the -COOH group, which contributes to their higher boiling points compared to hydrocarbons.

Catalysts provide an alternative reaction pathway with a lower activation energy, but they are not consumed in the reaction.

Chemisorption involves the formation of strong chemical bonds between the adsorbate and the surface, making it generally irreversible.

Circularly polarized light has no preferred direction of oscillation; the electric field vector rotates in a circular motion.

Colligative properties depend on the number of solute particles in a solution, not their identity.

Constraints can be hierarchical, meaning some constraints may take precedence over others in determining set membership.

The statement that 'all constraints must be numerical' is false; constraints can be based on various properties, not just numerical.

Not all coordination compounds are colored; the color depends on the nature of the metal and the ligands involved. Some coordination compounds can be colorless.

Diffraction gratings can produce multiple orders of maxima due to the constructive interference of light waves.

Diffraction can occur with any type of wave, including sound, light, and water waves.

In dynamic equilibrium, the rates of the forward and reverse reactions are equal, but the concentrations of reactants and products may not be equal.

The elastic potential energy stored in a stretched wire is given by U = (1/2) * F * x, which is proportional to the square of the extension.

Electric field lines point from positive to negative charges, indicating the direction of the electric field.

Electromagnetic waves are transverse waves that do not require a medium to propagate and travel at the speed of light in a vacuum.

Electrons have a negligible mass compared to protons and neutrons.

Enthalpy is an extensive property, meaning it depends on the amount of substance present.

Entropy is a measure of disorder in a system.
