Answer:
Structures of products has been shown below
Explanation:
- In claisen condensation, two ester molecules combines with each other through nucleophilic acyl substitution resulting formation of a
-ketoester. - At first, one ester molecule gets deprotonated in presence of a strong base e.g. NaOEt yielding a carbanion.
- The carbanion then gives nucleophilic acyl substitution reaction with another ester molecule to replace alkoxy group present in ester group
- General reaction mechanism of claisen condensation along with products of given esters are shown below.
Explanation:
For a compound to show hydrogen bonding it is necessary that the hydrogen atom of the compound should be attached to more electronegative atom like fluorine, oxygen or nitrogen.
For example,
,
and
all these compounds contain an electronegative atom attached to hydrogen atom.
Therefore, these pure compounds will exhibit hydrogen bonding.
Thus, we can conclude that out of the given options
,
and
are the pure compounds which will exhibit hydrogen bonding.
High temperature and low pressure<--Most likely
Low temperature and high pressure<----Less likely.
So the answer to this is Low temperature and high pressure.
Answer:
When hydrogen gas combines with nitrogen to form Ammonia the following chemical reaction will take place. Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat. In this case, Hydrogen and nitrogen react together to form ammonia.
