Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.
Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.
Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .

Storms are disturbances in atmospheric conditions. The four severe storms are thunderstorms, lightning, heavy rain, and blizzards.
<h3>What are blizzards?</h3>
Blizzards are the type of storm that includes high wind at 40 km/h and also have snow and cold air that makes the temperature drop and causes poor visibility.
Thunderstorms and lightning occur with high electrical charge release during high wind and rain. Heavy rains are severe types of storms as they can cause a flood.

The difference between the plant and animal cells is in their structures, and this makes their functions to differ. Some organelles are present in the plant cell which are absent in the animal cell and vice versa. The presence/absence of these organelles impact the kind of functions that can be carried out by each cell.
- The plant cell has a rigid cell wall made of polysaccharides while the animal cell lacks cell wall. The cell wall serves supportive functions in the plant and gives it a shape. Animal cells are more or less round in shape.
- Plant cells have chloroplasts while it is absent in the animal cell. the chloroplast contains chlorophyll, a green pigment that is responsible to absorbing radiant energy, As such, the chloroplast enables plant cells to carry out photosynthesis. Animals cells cannot synthesize their own foods.
- Plant cells have large central vacuole that stores water and other contents while animal cells have small vacuole
- Animal cells have centrioles while plant cells do not. The centrioles make mitotic division different between the two cells, although, the same result is obtained at the end of the day.

Answer:
3.4321229*10^23 molecules.
Explanation:
1 mole of CBr4 contains 6.0221409*10^23 molecules (Avogadro's Number).
The molar mass of this compound is 12.011 + 4(79.904)
= 331.627 g.
So the answer is (189/ 331.627) * 6.0221409*10^23
= 3.4321229*10^23 molecules.
