- The reaction in which we can't take back the product to reactant form .Or in simple words the reaction which is irreversible is called chemical reaction
Example:-
We cannot pull back the reaction to get wax back .
Atoms are composed of electrons in a cloud around a positive nucleus.
The sodium ion becomes hydrated. when sodium chloride dissolves in water, the sodium and chloride ions and the polar water molecules are strongly attracted to one another by ion-dipole interactions
Answer:
Answers are given below
Explanation:
(a) Aldehyde groups are reduced by sodium borohydride in methanol to give alcohol.
So, butanal produces butanol on reaction with sodium borohydride in methanol.
(b) Aldehyde forms cyanohydrin when they are treated with HCN with catalytic cyanide.
(c) Aldehydes are oxidized by potassium dichromate in dil. sulphuric acid to produce carboxylic acid.
(d) Aldehyde produces acetal with methanol and a trace amount of acid catalyst.
(e) Aldehyde gives condensation reaction with
to produce imine.
Structures of products for the given reaction has been shown below.
