The lone pair of electron present on the halogen atom overlaps with the adjacent pi bond electrons of the benzene ring and get delocalised. As a result of this the carbon-halogen bond strength increases and halogen atom can't be displaced easily.

Why haloalkanes gives cyano product with kcn and gives isocyano with agcn?

Haloalkanes react with KCN to form nitriles because CN- acts as a nucleophile attacking the carbon of the halogen atom, leading to substitution. On the other hand, with AgCN, the reaction proceeds through an isocyanide intermediate due to the ability of Ag+ to stabilize the cyanide ion, promoting nucleophilic addition to the carbon of the halogen atom.


Why carbonyl compounds will not react with hydrogen halides?

Because silicon will react and make a compound with carbon and create a new element called chlorine. You can also create a brand new element called bean using hydrolic acid and a thermometer. Also carbonyl is a meat and will not fuse with hydrogen because it is vegetarian.


How to convert benzyl alcohol to 2-phenylethanoic acid?

To convert benzyl alcohol to 2-phenylethanoic acid, you would first need to oxidize the alcohol group to a carboxylic acid group. This can be achieved by using a strong oxidizing agent such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). The benzyl alcohol would be converted to benzaldehyde, and further oxidation would yield 2-phenylethanoic acid. The reaction would typically be carried out under acidic conditions to facilitate the oxidation process.


What happens to the mass of the metal anode as the cell continues to operate?

It depends on the specifics of the cell, but in most simple galvanic cells, the anode slowly dissolves into solution.


What gives strenght to a cell?

The cell membrane gives strength to animal cells and the cell wall gives strength to plant cells.

What is the SN1 reaction that produces ethanol from chloroethane?

In an SN1 reaction, chloroethane undergoes nucleophilic substitution to form ethanol. The chloroethane molecule first undergoes heterolytic cleavage to form a carbocation intermediate. Then, a nucleophile such as water attacks the carbocation, resulting in the formation of ethanol as the final product.

Why does aqueous KOH facilitate substitution reaction while alcoholic KOH facilitate elimination reaction?

KOH in Water gives OH- ions which are strong nucleophile and facilitate the substitution reaction while KOH in ethyl alcohol produces C2H5-O- ions which due to larger size observe hindrance when attack on alpha carbon so as a strong base it removes hydrogen from beta carbon and is responsible for elimination reaction.

How do you know that substitution gives the answer to a system of equations?

You put in the answers you got for your variables into one of the equations. If it gives you the correct answer then you solved it, if it's different then either it doesn't work or one of the steps wasn't completed correctly or at all.


What r products of chlorine and humic acid reaction?

Chlorinated products of humic acid (or polyphenols) are formed (by substitution and or addition reactions) which gives them an awefull odor.

This is a radioactive chemical element.


Did porphyry cool quickly or slowly?

Porphyry cooled slowly, allowing large crystals to form within a fine-grained matrix. This slow cooling process gives porphyry its characteristic appearance of large crystals embedded in a finer grained groundmass.
