<h2>Heptene formed is -</h2><h2>

</h2>
Explanation:
The two possibilities when the peroxide is not present
+ HBr →
In presence peroxide,
≡
+ HBr →
- When peroxides are present in the reaction mixture, hydrogen bromide adds to the triple bond of heptane with regioselectivity.
- This reaction is opposite to that of Markovnikov's rule which says that when asymmetrical alkene reacts with a protic acid HX, then the hydrogen of an acid is attached to the carbon with more in number of hydrogen substituents, and the halide (X) group is attached to the carbon with more in number of substituents of alkyl.
- One mole of HBr adds to one mole of 1-heptane.
- The structure of heptene formed is -

Answer:
C = 0.08M
Explanation:
molar mass of AlCl3
Al =27
Cl = 35.5
27+3(35.5) =133.5g/mol
n= mass/Molar mass
n =CV
CV = mass/molar mass
C x 500 x 10^-³ = 5/133.5
C x 500 x 10^-³ = 0.04
C = 0.04/500 x 10^-³
C = 0.08M
Option C
PCR technique would you rely on to assist with analysis
<u>Explanation:</u>
Experts elaborate this tiny specimen by a means acknowledged as a polymerase chain reaction, or PCR. PCR produces replicas of the DNA significant like DNA duplicates itself in a cell, offering virtually any coveted measure of the ancestral element.
Following the accumulation of biological matter from a crime picture, the DNA is beginning derived from its biological source element and then estimated to assess the number of DNA rescued. Subsequent detaching the DNA from its cells, precise areas are imitated with a procedure acknowledged as the polymerase chain reaction, or PCR.
When an acid and a base react together the products they form are an ionic compound or salt and water.
Answer:
The moles of gas is 0.009474 moles.
Explanation:
Given that,
Volume = 526 mL
Pressure = 346 mmHg
Temperature = 35.0°C
We need to calculate the moles of gas
Using formula of ideal gas

Where, P = pressure
V = volume
R = gas constant
T = temperature
Put the value into the formula


Hence, The moles of gas is 0.009474 moles.
