Aluminum commonly forms stable +3 oxidation state compounds.

Thallium is known for forming a stable +3 oxidation state.

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

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

Lanthanum (La) and Cerium (Ce) are both f-block elements, belonging to the lanthanide series.

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

Complementary angles are two angles whose sum is 90 degrees. All the given pairs meet this criterion.

Supplementary angles are two angles that add up to 180 degrees. An acute angle (less than 90 degrees) and an obtuse angle (more than 90 degrees) can add up to 180 degrees.

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.

The first pair has the same slope (2/3) and thus represents parallel lines.

The first pair represents parallel lines, which means they will never intersect, hence no solution.

N2 and CO both have a bond order of 3.

The HCF of 15 and 28 is 1, making them coprime.

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

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

The mass of an electron is significantly less than that of protons and neutrons.

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.
