Answer:
Charges flow through a closed path called a circuit. Current flows because negatively charged particles are attracted to positively charged particles at the other end of the circuit.
Answer:
C3H7OH → C3H6 + H20
Explanation:
If we look at the reactant and the product we will realize that the reactant is an alcohol while the product is an alkene. The reaction involves acid catalysed elimination of water from an alcohol.
Water is a good leaving group, hence an important synthetic route to alkenes is the acid catalysed elimination of water from alcohols. Hence the conversion represented by C3H7OH → C3H6 + H20 is an elimination reaction in which water is the leaving group.
Answer:
Compound A: 1-bromo-1-methylcyclohexane
Compound B: 1-methylcyclohex-1-ene
Explanation:
In this question, we can start with the <u>I.D.H</u> (<em>hydrogen deficiency index</em>):
In the formula we have 7 carbons, 13 hydrogens, and 1 Br, so:
We have an <u>I.D.H value of one</u>. This indicates that we can have a <u>cyclic structure or a double bond</u>.
We have to keep in mind that the Br atom must be bonded to a t<u>ertiary carbon</u>. <u>We can not have a double bond</u> because in the ozonolysis reaction we have only <u>1 product</u>, therefore, we can not have a double bond in the initial molecule (if we have a double bond in the initial molecule we will have more than 1 product in the ozonolysis reaction).
With this in mind, we will have a <u>cyclic structure</u>. If we have 7 carbons and we need a tertiary alkyl halide. We can have a cyclic structure of 6 members and a methyl group bonded to a carbon that also is bonded to a Br atom <u>(1-bromo-1-methylcyclohexane).</u>
In the reaction with 
we will have an <u>elimination reaction</u>. In other words, we have the production of a double bond inside of the cyclic structure <u>(1-methylcyclohex-1-ene)</u>.
See figure 1 for further explanations.

Answer:
Chiral:
3-Methyl-2-butanol
Achiral:
1-Pentanol
3-Pentanol
3-Methyl-1-butanol
Explanation:
Only the molecule that bears a carbon atom surrounded by 4 different groups can be said to be Chiral, the other molecules don't satisfy this property.
The correct option is C. Nitrogen gas has the highest percentage by volume of all the gases that make up the air.
The composition of the air is as follows:
nitrogen = 78.09%
Oxygen = 20.95%
Argon = 0.93%
Carbon dioxide = 0.04%
water vapour = traces amount.
