The solution to the question above is shown on the second uploaded image
Explanation:
This talks on the concept of reaction of Grignard reagent with carbonyl compounds. Carbonyl compounds (aldehydes and ketones) are extremely reactive towards the nucleophile due to their highly electrophilic nature. Carbonyl groups include a carbon which is attached to the oxygen atom which highly electronegative as compared to the carbon and hence attracts the shared pair of electrons which results in the generation of partial positive character on the carbonyl carbon.
Grignard reagents on reaction with carbonyl compounds carry out a nucleophilic addition reaction which on treatment with water gives a corresponding alcohol.
For the First reaction
The reaction of Grignard reagent with the ketone is shown on the third uploaded image :
i.e Butan-2-one reacts with methyl magnesium bromide in presence of
to form 2-methylbutan-2-ol.
For the Second reaction
The reaction of Grignard reagent with the aldehyde is shown on the fourth uploaded image :
I.e Butyraldehyde reacts with ethyl magnesium bromide in presence of
to form hexan-3-ol.
Answer: D=8.27 g/cm³
Explanation:
Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.
With this equation, the m³ and kg cancel out, and we are left with g/cm³.
D=8.27 g/cm³
Answer:
See explanation and image attached
Explanation:
Here attached are resonance forms of pyrrole and pyridine. The images were obtained from quora and researchgate respectively.
Now, we can see that in the resonance forms of pyrrole, the nitrogen atom in the heterocycle has a formal charge of +1. However, in the six membered pyridine hetrocycle, the nitrogen atom may have a formal charge of -1 or +1 as shown in the canonical structures attached. The structures in which nitrogen has a +1 formal charge in pyridine are comparable to structures obtained from pyrrole. These structures have less contribution to the structure of pyridine.
