Why does cyclohexanone form a cyanohydrin but 2 2 6 trimethylcyclohexanone is unreactive to HCN?

Substituents at adjacent carbon atoms to ketone are responsible for stearic hindrance so the attack of cyanide ion at ketonic carbon is almost impossible.

What don't the noble gases form?
Noble gases doesn't form many compounds because they are extremely unreactive.
Which element exisit in its pure form?
most noble gases exist in their pure form because they are so unreactive
The noble gases include helium neon argon krypton xenon and radon. What property do these elements share?
They readily form compounds with other elements.
What characteristics do atoms of mangnaese-55 iron-56 and nickel-58 have in common?
They are all transition elements, so all are fairly unreactive, form coloured compounds and are hard and strong elements, they can be used to make alloys.
Are noble gases completely unreactive?
Noble gases are generally unreactive because they have a full outer electron shell, making them stable. They do not readily form compounds, but under certain conditions, such as high temperatures or pressures, they can react with other elements. However, compared to other elements, noble gases have a significantly lower reactivity.
What happens when alc KCN is added to benzaldehyde?
The CN― adds to the carbonyl carbon to form a cyanohydrin attached to a benzyl group.
What don't the noble gases form?
Noble gases doesn't form many compounds because they are extremely unreactive.
Which element exisit in its pure form?
most noble gases exist in their pure form because they are so unreactive
What is an unreactive gas element that in radioactive form is a byproduct of most nuclear explosions?
Helium (or alpha particles)
Does gold form compounds?
Although gold is unreactive, it forms many compounds with a range of oxidation states.
Which family tends to be chemically unreactive?
The noble gases, column 18 in a wide form periodic table.
Why helium does not form compounds?
Because it has 2 electrons which fill up its electron shell, making it unreactive and stable.
Why are gold and silver not found as an ore?
Because silver and gold are native metals that are found in its pure form as they are unreactive!
Is malonate an inhibitor of fumarate?
Yes. Malonate is a competitive inhibitor because it is unreactive as dehydrogenation cannot occur. Malonate is in the cis form, whereas fumarate is in the trans form.
What would form the fewest covalent bonds oxygen or neon?
Neon, as it is a noble gas, is highly unreactive, and will hardly form any bonds, let alone covalent ones.
What elements can be found in elemental form uncombined with other elements on earth?
Highly unreactive elements that will not chemically combine include: Platinum (Pt) Gold (Au) Helium (He) Argon (Ar) Krypton (Xe) Neon (Ne) The first two are unreactive because they are at the bottom of the metals reactivity series. The rest are unreactive because they are part of the inert gases.
Why don't the noble glass tend to form chemical bonds?
The noble gases are unreactive because their valence shells are full, making them stable.
