Answer: Option (3) is the correct answer.

Explanation:

When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.

When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.

When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.

Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.

A chemical reaction with an initial quantity of 1.35 moles of gas is performed in a 4.50-L flask at 24.7°C and under 1.07 atm of

nexus9112 [7]

Answer:

0.488 mol

Explanation:

By the ideal gas law:

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.082 atm.L/mol.K), and T is the temperature in K. Thus, after the reaction:

P = 2.92 atm

V = 4.50 L

T = 55.2°C + 273 = 328.2 K

PV = nRT

n = PV/RT

n = (2.92*4.50)/(0.082*328.2)

n = 0.488 mol
