  Well think of the carbocation of that molecule. Taking off the OH atom will give you a secondary carbocation which by itself is a major product. However if you notice, a tertiary carbocation can also be formed when the hydrogen on the carbon of the cyclubutane part of the molecule, migrates to the c2 of the propyl group.

QUESTION POSTED AT 28/02/2020 - 04:29 PM

What happens to the temperature of water between the time ice melts and water boils (this is partially quoted from a question)? Also, what change occurs in temperature after water starts boiling (this is also from a booklet)? Thank you and please explain your thoughts. This is based on the phase changes of water, and you should refer to a graph on the phase changes of water.

Your first statement is very ambiguous so I will give it the best shot as to what you are saying.
The temperature, between the point of ice melting and water boiling, is increasing as water is in its liquid state.
Now during a phase change, or while the water is boiling, the temperature remains constant because the energy being added is being consumed to complete the phase change.
But if you're looking at the phase change graph, the points of positive slopes, are moments when energy is increasing as the water, in whatever state, is increasing. But when the slope of the graph is 0, the water is changing phases and the temperature remains constant! I hope I explained that so you could understand it, and I hope this helps you!

How do you draw molecular compound structures? Example: C2H2

It's hard to describe how to draw these compounds. However, I will try my best using the example provided. The example provided would look like this H-C(triple bond)C-H. First it is important to know how many electrons you are working with. In this case there are ten electrons. 8 from carbon and 2 from hydrogen. After you know this, you can draw the structure. Each carbon atom needs an octet or eight atoms surrounding it. Creating a triple bond with the other carbon and a single bond with one hydrogen atom allows for this to happen. It takes practice to master drawing structures but with time it gets easier! I hope this helped!

Which molecule is polar, based on structure? sulfur dioxide carbon disulphide ethylene carbon tetrachloride

Answer:  Sulphur Dioxide

Explanation:  Polarity of the molecule is basically based on -

a) Electro negativity of the individual atoms

b) Structure of the molecule as change will dipole moment or asymmetric structure will lead to the polar molecule.

Sulfur Dioxide has bent structure with 2 lone pairs and 2 bond pairs. . Thus the molecule is polar

Carbon disulfide has linear structure. Thus there will be no change in dipole moment in the structure thus in non polar.

Ethylene molecule is the most linear molecule thus cannot be polar.

Carbon Tetra chloride is in shape of Tetrahedron thus it is also non polar as no net change in dipole moment can be seen.

B.Like ''biology'' the name for the biosphere comes from the Greek world for life. c. Light and heat from the sun don't affect the biosphere. D.The biosphere gets resources from Earth's crust, hydrosphere and atmophere

Answer: c. Light and heat from the sun don't affect the biosphere.

Explanation:

The biosphere is the sphere where living beings such as plants, animals, microbes, humans and others survive, reproduce and lead their life cycle.  

The atmosphere is a sphere of the earth. It consists of collection of different gas called as air. It protects the biosphere by absorbing the incident harmful radiations along with heat coming from the sun.

Strontium 90 (sr-90, a radioactive isotope of strontium, is present in the fallout resulting from nuclear explosions. it is especially hazardous to animal life, including humans, because, upon ingestion of contaminated food, it is absorbed into the bone structure. its half-life is 27 years. if the amount of sr-90 in a certain area is found to be four times the "safe" level, find how much time must elapse before the safe level is reached.

This is a relatively easy half-life problem.
Whenever a half-life has expired, one half of the radioactive isotope will no longer be present.
When 2 half-lives have occurred, then one quarter of the isotope remains.
Therefore, the strontium - 90 will be at a safe level in 54 years.
