Such reactions are known as HYDRATION and are performed in presence of sulphuric acid.
Electrophilic addition reaction
Also, it's a hydration reaction, since you are adding water to the alkene (in this case, ethene).
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
Potassium dichromate is orange and when it reacts with ethanol which is a primary alcohol it is going to oxidise it to form aldehyde which is colorless. so the color change is from Orange to Colorless. :)
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
One hydrazine reacts with two acetone to yield two 2-propanol and one nitrogen (gas).
ethanol dissolves in water because both ethanol and water are polar. there is no other chemical reaction
Ethene reacts with water in presence of sulphuric acid and forms Ethyl alcohol.
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
Metallic sodium reacts vigorously with ethanol to form sodium ethanoate.
Ethanol only.
They may be ethene, propene! ethyne, propyne and all the unsaturated hydrocarbons
Yes, predominantly. BaC2 reacts with water to form ethene, (acetylene) as does calcium carbide.
addition reactions. I was looking up the same question and found it!!!
There is no specific name for 'something which reacts with vinegar'. Vinegar is ethanoic acid and reacts with various substance. Some examples are alkalis like sodium hydroxide, metal carbonates and alcohols such as ethanol.
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
Potassium dichromate is orange and when it reacts with ethanol which is a primary alcohol it is going to oxidise it to form aldehyde which is colorless. so the color change is from Orange to Colorless. :)
