Neodymium (Nd) and Plutonium (Pu) are both f-block elements.

D-Glucose and L-Glucose are mirror images of each other, making them enantiomers.

1-pentanol and 2-pentanol differ in the position of the hydroxyl group, making them structural isomers.

C and N will form a bond with the highest bond order of 3, as seen in the molecule CN.

C and N will form a stable diatomic molecule as they have suitable bond orders and electron configurations.

D-Glucose and L-Glucose are mirror images of each other, making them enantiomers.

C2H6 (ethane) and C2H5OH (ethanol) have different functional groups, making them functional isomers.

Cis-2-butene and trans-2-butene differ in the arrangement of groups around the double bond, making them geometric isomers.

Ethyl alcohol (ethanol) and dimethyl ether have the same molecular formula but different structures.

Cerium (Ce) and Lanthanum (La) are both f-block elements.

Cerium (Ce) and Lanthanum (La) are both lanthanides, which are f-block elements.

N2 and CO both have a bond order of 3.

The electron is the only particle listed that has a negative charge.

The electron has the least mass compared to protons and neutrons.

Among the given particles, the electron has the smallest mass, approximately 1/1836 of a proton.

Beta decay involves the emission of beta particles, which are electrons or positrons.

Pions are mesons, not baryons. Baryons are particles made up of three quarks, while mesons are made up of a quark and an antiquark.

Electrons are not constituents of the nucleus; they orbit around the nucleus, while protons and neutrons are found within it.

An electron is not a nucleon; nucleons are particles found in the nucleus, which include protons and neutrons.

Electrons are not found in the nucleus; they orbit around the nucleus, while protons and neutrons are the constituents of the nucleus.

Electrons are not found in the nucleus; they orbit around it.

Interference is a phenomenon that can be explained by the wave nature of light, as it involves the superposition of light waves.

All of the mentioned phenomena (photoelectric effect, Compton effect, and diffraction) demonstrate the wave-particle duality of light.

Diffraction is a phenomenon that leads to interference patterns, as it involves the bending of waves around obstacles.

Water droplets on a leaf demonstrate surface tension, as the cohesive forces between water molecules create a 'skin' on the surface.

Surface tension is responsible for capillary action, allowing liquids to rise in narrow tubes.

Viscosity describes the resistance of a fluid to flow, which is a key factor in fluid flow resistance.

Conduction is a mode of heat transfer and is not a characteristic of wave motion, while reflection, refraction, and diffraction are.

Conduction is a process of heat transfer and is not a characteristic of wave phenomena.

Floating of heavy objects is not a consequence of surface tension; it is due to buoyancy, while the other options are directly related to surface tension.
