Answer:
Reaction mechanism has been given below
Explanation:
- Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
- Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
- In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
- Reaction mechanism has been shown below.
Answer:
The number and the kinds of atoms in the compound
Explanation:
- A chemical formula of a compound contains symbols o the atoms of the elements present in the compound as well as the number of atoms of each element in the form of subscripts.
- Therefore it helps us to know the elements in a compound and the number of atoms in the compounds.
Answer: A solid has a defined shape and volume. A common example is ice.
A liquid has a defined volume, but can change state. An example is liquid water.
A gas has neither a defined shape nor volume. Water vapor is an example of a gas
Answer:
There are significant environmental impacts associated with coal mining and use. It could require the removal of massive amounts of top soil, leading to erosion, loss of habitat and pollution. Coal mining causes acid mine drainage, which causes heavy metals to dissolve and seep into ground and surface water.
