Explanation

sp hybridization: When one s orbital and one p orbital mix, they form two sp hybrid orbitals.

These hybrid orbitals are oriented linearly (180 degrees apart) from each other.

This linear geometry is characteristic of molecules with only two electron groups around a central atom.

Examples include acetylene (C2H2) and carbon monoxide (CO). 

Explanation

Acetophenone has the chemical formula C6H5COCH3

Explanation

Maltose is not a macromolecule.

Explanation

The Born-Haber cycle is best example of Hess's law. 

The Born-Haber cycle uses the concept of Hess's law to calculate the lattice energy of an ionic compound by breaking down the formation of the compound into several smaller, easier-to-quantify steps

Explanation

Hemoglobin is a large protein (macromolecule) made up of four polypeptide chains, each with a heme group.

It contains approximately 68,000 atoms, including carbon, hydrogen, oxygen, nitrogen, iron, and sulfur.

Explanation

Lithium aluminium hydride (LiAlH₄) is a strong reducing agent.

It reduces carboxylic acids to primary alcohols effectively.

Explanation

The Born-Haber cycle is a thermodynamic cycle used to calculate the lattice energy of ionic compounds.

It uses known values like ionization energy, electron affinity, and enthalpies to find the unknown lattice energy.

Explanation

 In aromatic sulfonation, sulfur trioxide (SO3) is the actual attacking species, reacting with the aromatic ring to form a sulfonic acid. 

Explanation

Substitution reactions are given by alkanes whereas unsaturated hydrocarbons like alkenes and alkynes undergo addition reactions.

Explanation

Grignard reagent reacts with water to give alkane.

This is because Grignard reagent acts as a strong base that reacts with the active hydrogen of water that is -H of  H2O  to form alkane as shown below :
