Enzymes are biological molecules (specifically proteins) that accelerate chemical reactions. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Natural rubber is poly-cis-ispropene. It is polymer of 2-methyl-1, 3-butadiene (isoperene).

The equivalent conductance of strong electrolyte is increased by dilution, because its value is equal to the multiple of K_v and the volume of solution. By making dilution the volume of solution increases which also increase the value of equivalent conductivity.

Vinegar is an aqueous solution of acetic acid and trace chemicals that may include flavorings. It consists of 7 to 8% acetic acid.

Among all the given options, option c has the correct order of increasing reactivity.

RCOCl (Acid halide) < RCONH₂ (Amide) < RCOOR (Ester)

Hexamethylenetetramine is used for the treatment of urinary tract infections. It decomposes at an acidic pH to form formaldehyde and ammonia.

Most of the transition metals show paramagnetic behaviour. The unpaired electrons in (n - 1)d orbitals are responsible for the magnetic properties.

Cannizzaro's reaction is the reaction where benzaldehyde changes in to benzyl alcohol.

An asymmetric carbon atom is defined as a carbon within an organic compound that contains four different atoms or groups of atoms (substituents) bonded to it.

Cadmium rods are used to absorb neutrons in nuclear reactors, because cadmium is neutron absorber.
