PLEASE MARK ME AS THE BRAINLIEST... ;)
Properties of a compound is completely different from their elements.
Water is composed by hydrogen and oxygen.
For example, the boiling point of oxygen is - 183 °C and hydrogen is - 253 °C, meanwhile, water has a boiling point of 100°C
Another example is when you put a burning wooden splint into oxygen, it burns more brightly. Put it in hydrogen, you may hear a "pop" sound, or even explode when large amount of hydrogen. But if u put a burning splint in water, it goes off.
Answer:
Structure of the product has been shown below
Explanation:
- N atom in aniline acts as a nucleophile and carbonyl group of propanoic acid acts as an electrophilic center.
- A nucleophilic acyl substitution reaction occurs on mixing and heating mixture of aniline and propanoic acid.
- In this reaction an amide is formed.
- Reaction mechanism goes through addition-ellimination pathway at carbonyl center.
- Full reaction mechanism has been shown below.
The energy will be transferred from the warmer object to the freezing object .
