Benzene (C6H6) exhibits resonance due to the delocalization of electrons in the sp2 hybridized carbon atoms forming a cyclic structure.

Ozone (O3) exhibits resonance due to the delocalization of electrons between the three oxygen atoms.

Sulfuric acid is a strong acid that completely dissociates in water, making it a strong electrolyte.

HCl is a strong acid that completely dissociates in water, while HF, H2CO3, and CH3COOH are weak acids.

All of the listed acids (HCl, H2SO4, HNO3) are strong acids that can effectively dissolve metals.

HCl is a strong acid that completely dissociates in water, while HF, H2CO3, and CH3COOH are weak acids.

Sulfuric acid is the primary acid used in lead-acid batteries, which are commonly found in cars.

Cyanide solution is used in the leaching process to dissolve gold from its ore.

Cyanide solution is commonly used in the leaching process to extract gold from its ores.

Sulfuric acid is commonly used in the leaching process to dissolve metal ores.

Hydrochloric acid is commonly used in the pickling process to remove rust and scale from metals.

Nitric acid is widely used in the production of fertilizers, particularly ammonium nitrate.

H2SO4 (sulfuric acid) is a diprotic acid, meaning it can donate two protons (H+ ions) in solution.

All of the listed acids (phosphoric, sulfuric, and nitric) are used in the production of various fertilizers.

Sodium hydroxide is commonly used in the saponification process to produce soap from fats and oils.

Sodium hydroxide is commonly used in the saponification process to produce soap.

Real gases deviate from ideal behavior at high pressures due to increased intermolecular forces and the volume occupied by gas molecules.

The bond angle in water is approximately 104.5 degrees due to the repulsion of the two lone pairs on the oxygen atom.

Lipids, particularly triglycerides, are primarily responsible for energy storage in animals.

The O-H bond is the most polar due to the high electronegativity difference between oxygen and hydrogen.

[Ni(CN)4]2- is a square planar complex, while the others typically exhibit octahedral geometry.

HCl acts as a Brønsted-Lowry acid because it donates a proton (H+).

NH3 acts as a Brønsted-Lowry base because it can accept a proton.

BF3 (boron trifluoride) is a Lewis acid because it can accept an electron pair.

2-hexene has a double bond that allows for cis and trans configurations.

2-butanol has a chiral center and can exist as two enantiomers, thus exhibiting optical isomerism.

2-bromobutane can undergo E1 elimination due to the stability of the carbocation formed during the reaction.

Tertiary alkyl halides are most favorable for E2 reactions, but primary and vinyl halides can also undergo E2 under certain conditions.

3-bromopropane can undergo an SN1 reaction due to the stability of the tertiary carbocation that forms during the reaction.

Benzene can undergo electrophilic substitution reactions due to its stable aromatic system, while the other compounds cannot.
