Explanation

The nickname given to Mr. Chipping by his students is Mr. Chips. 

Explanation

 Hydroxylation of alkene can be carried out by  alkaline KMnO4. 

Hydroxylation refers to the addition of two hydroxyl (OH) groups across a carbon-carbon double bond in an alkene.

Cold, dilute, alkaline potassium permanganate (KMnO4) is a common reagent used for this reaction.

It reacts with the alkene to form a vicinal diol (a molecule with two hydroxyl groups on adjacent carbon atoms). 

Explanation

 Ethene (also known as ethylene) is a naturally occurring plant hormone that plays a key role in fruit ripening.

It is commonly used commercially to artificially ripen fruits like bananas, tomatoes, and avocados. 

Explanation

 Xenon is the most polarized noble gas due to its large size and electron cloud,

This makes it more susceptible to distortion by external electric fields. 

Explanation

Explanation

A heterocyclic compound is a ring structure that contains at least one atom other than carbon in the ring.

Pyridine has a nitrogen atom in its ring structure, making it a heterocyclic compound. 

Explanation

In the borax bead test, cobalt ions (Co²+) react with borax to form cobalt metaborate (Co(BO2)2), which produces a distinct blue color. 

Explanation

 Bakelite is a thermosetting polymer. 

Thermosetting polymers are plastics that undergo a permanent chemical change when heated,

Forming cross-links that make them rigid and unable to be reshaped or melted after curing.

Bakelite is a classic example of a thermosetting polymer,

Formed through the condensation reaction of phenol and formaldehyde.

It is often used in applications like electrical insulation and handles. 

Explanation

 Newspaper, and paper products in general, can typically be recycled around 5 to 7 times

Before the fibers become too short and weak to be reused effectively in the recycling process.
