1) As can be seen from any 1H NMR chemical shift ppm tables, hydrogens which have δ values from 2ppm to 2.3ppm are hydrogens from carbon which is bonded to a carbonyl group. From this, we can conclude that our hydrogens belong to the type, but from 2 different alkyl groups because of 2 different signals.
2) So, one alkyl group is CH3 and second one can be CH or CH2.
3) If we know that ratio between two types of hydrogens is 3:2, it can be concluded that second alkyl group is CH2.
4) Finally, we don't have any other signals and it indicates that part of the compound which continues on CH2 is exactly the same as the first part.
The ratio remains the same, 3:2 ie 6:4
Answer:
Deposition
Explanation:
Deposition: The gaseous substance turns directly into a solid without undergoing the liquid phase
Gypsum has the same hardness as a fingernail
Answer:
The answer to your questions are given below
Explanation:
The answer to the questions given above can simply be obtained by writing the electronic configuration of each atom.
The electronic configuration of each atoms can be written as follow:
Fluorine, F (9) => 1s² 2s²2p⁵
Sodium, Na (11) => [Ne] 3s¹
Helium, He (2) => 1s²
Calcium, Ca (20) => [Ar] s²
Nitrogen, N (7) => 1s² 2s²2p³
Sulphur, S (16) => [Ne] 3s²3p⁴
Answer:
Monsoon seasonal diseases can be avoided by keeping surroundings clean, removing stagnant water, eating homemade food, washing hands properly, eating clean and drinking boiled water.
Explanation:
1. Make efforts in making the environment mosquito free by proper cleaning and removing stagnant water as well.
2. Use mosquito repellant, mainly net that has no side effects and is ecofriendly.
3. Avoid moving to crowded places to prevent viral infections.
4. Consume food made at home and boiled water.
5. Wash hands before consuming food.
