Hydrogen isomerism is not a recognized type of isomerism in chemistry.

Tensile modulus is not a standard term; the correct terms are Young's modulus, shear modulus, and bulk modulus.

Thermal stress is a result of temperature changes, while tensile, compressive, and shear stresses are types of mechanical stress.

Joule is a unit of energy, not power. Power is measured in Watts, Kilowatts, and Horsepower.

A potentiometer is not used for direct resistance measurement; it is primarily used for voltage measurements.

Calcium is not an alkali metal; it is an alkaline earth metal.

Cyclooctatetraene is not aromatic because it does not satisfy Huckel's rule; it is non-planar and does not have a continuous overlap of p-orbitals.

The kinetic molecular theory assumes that gas particles do not attract or repel each other.

Aluminum is not an s-block element; it is a p-block element.

f(x) = 1/x is not continuous at x = 0 as it is undefined there.

Copper is known to be one of the best conductors of heat among the given options.

The conjugate of a complex number a + bi is a - bi. Thus, the conjugate of 2 - 3i is 2 + 3i.

The conjugate of a complex number a + bi is a - bi. Thus, the conjugate of 5 - 3i is 5 + 3i.

1 kilometer is equal to 1000 meters, hence the conversion factor is 1000.

1 kilometer is equal to 1000 meters.

1 kilometer is equal to 1000 meters.

The dimensional formula for electric charge is [M^1 L^2 T^-3 A^-1], derived from the definition of current.

Frequency has the dimensional formula [M^0 L^0 T^-1].

The van der Waals equation is (P + a(n/V)^2)(V - nb) = nRT.

Ethyne, also known as acetylene, has the formula C2H2, which indicates it is an alkyne.

The double angle formula states that sin(2A) = 2sinAcosA.

The compound is a ketone with a four-carbon chain, and the carbonyl group is on the second carbon, hence it is Butan-2-one.

C3H6 corresponds to propene, which is an alkene with a double bond.

The compound has 3 carbons in the longest chain and a carboxylic acid group, hence it is Propanoic acid.

C5H10 corresponds to pentane, which is a straight-chain alkane with 5 carbon atoms.

C6H12 is a straight-chain alkane with 6 carbons, which is named Hexane.

The compound has a phenyl group attached to a butanoic acid structure, making it Phenylbutanoic acid.

The compound has a phenyl group attached to an ethyl group, making it Ethylbenzene.

The longest carbon chain has 5 carbons, and there is a methyl group on the second carbon, making it 2-Methylbutane.

The longest chain has four carbons, and the hydroxyl group is on the first carbon, with a methyl group on the second carbon, making it 2-Methylbutan-1-ol.
