Answer:
Identify the indicated protons in the following molecules as unrelated, homotopic, enantiotopic, or diastereotopic. a) Methyls a & b: _________ b) Ha & Hc: ________
Explanation:
Homotopic hydrogens:
Consider two hydrogens in the given molecule and replace one by one with a different atom say for example deuterium, then if the two molecules formed by replacing hydrogens are the same then the two hydrogens are called homotopic hydrogens.
After replacing the two hydrogens with a different atom then, enantiomers are formed then, the two hydrogens are called enantiotopic hydrogens.
After replacing the two hydrogens with a different atom then, diastereomers are formed then, the two hydrogens are called diastereotopic hydrogens.
In the methyl group, select two hydrogens and replace one hydrogen atom with a D-atom name the compound.
Again replace another hydrogen atom with D-atom.
Name it.
If both are the same then, the hydrogens are homotopic and they are shown below:
Hence, they are homotopic protons.

Paratroopers not hurt while landing because when they get to the ground, they keep their knees and feet together helping them to land properly.

The mass number of aluminium hydroxide is 78 thus, the number of moles in 0.745 g is:
no. of moles= mass/ RFM
= 0.745/78
=0.00955moles
Therefore the 0.00955 moles should be in the 35.18 ml
therefore 1000ml of the solution will have:
(0.00955ml×1000ml)/35.18
=0.2715moles
The solution will be 0.27M hydrochloric acid
The answer is it changes the texture (shape and size) of the grains.
<u>Explanation</u>:
- During changeability, the protolith experiences changes in the texture of the stone and the mineral make up of the stone. These progressions happen because of the progressions brought about by physical or substance conditions, which for the most part happen in the strong state.
- Because of these progressions, rocks experience changes in temperature and pressure and might be exposed to the differential pressure and aqueous liquids. It likewise happens because of the strength of certain minerals just under specific conditions. These progressions bring about causing the substance responses which may prompt change fit as a fiddle and size.
