In CCl4, the central carbon atom is sp3 hybridized, forming a tetrahedral geometry.

CO2 has a linear geometry due to the sp hybridization of the carbon atom.

BeCl2 has two bonding pairs and no lone pairs, resulting in a linear molecular geometry.

BeCl2 has two bonding pairs and no lone pairs, resulting in a linear shape.

CH4 has a tetrahedral shape due to sp3 hybridization of the carbon atom.

PCl5 has five bonding pairs and no lone pairs, resulting in a trigonal bipyramidal geometry.

C2H4 (ethylene) has a carbon-carbon double bond, and each carbon is sp2 hybridized.

O2+ has a bond order of 2.5, which is higher than O2 (2), O2- (1.5), and O2 2- (1).

In this reaction, sodium (Na) is oxidized as it loses electrons to form Na+.

In the given reaction, MnO4- is reduced to Mn^2+.

F2 is the strongest oxidizing agent among the halogens due to its high electronegativity and ability to gain electrons.

Matrices are versatile mathematical structures that can represent data in multiple dimensions and are widely used in various fields, including computer science, engineering, and statistics.

The sum of probabilities of all possible outcomes must equal 1, which is a fundamental principle in probability theory.

A convex lens can produce both real images (when the object is outside the focal length) and virtual images (when the object is within the focal length).

In a geometric progression, the ratio of consecutive terms is indeed constant, which defines the progression.

In a kite, one pair of opposite angles are equal, while the other properties do not hold true.

In a parallelogram, the diagonals bisect each other, which is a defining property of parallelograms.

A potentiometer requires a constant current to ensure accurate measurements of voltage.

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

In a rhombus, while all sides are equal and diagonals bisect each other at right angles, the diagonals are not equal in length.

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.

In an arithmetic progression, the difference between any two consecutive terms is indeed constant, which defines the sequence.

Angles subtended by the same arc at the circumference of a circle are equal.
