Propose a structure for an aromatic hydrocarbon, C9H12, that can form two C9H11Cl products on substitution of a hydrogen on the

Crank

Answer:

Explanation:

From the given study,

the molecular formula of the given aromatic compound = C9H12

the first process we suppose to carry out is to calculate the double bond equivalence.

So, the double bond equivalence $DBE = {N_C+1-(\dfrac{(N_H+N_{Cl})-N_H}{2}) }$

$DBE = {9+1-(\dfrac{(12+0)-0}{2}) }$

DBE = 4

Hence, the aromatic compound possesses 4 double bonds, this signifies that the might be a presence of benzene ring.

The substitutional products of the aromatic hydrocarbon C9H12 can be seen in the attached file below.

What is the mass of oxygen gas in a 12.2 L

baherus [9]

Answer:

grams O₂ = 134 grams

Explanation:

PV = nRT => n = PV/RT

P = 8.15atm

V = 12.2 Liters

R = 0.08206L·atm/mol·K

T = 16.0°C + 273 = 289K

n = (8.15atm)(12.2L)/(0.08206L·atm/mol·K)(289K) = 4.2 moles O₂

grams O₂ = 4.2 moles O₂ x 32g/mol = 134 grams O₂
